The goal 143 is to achieve long-term monitoring of bright blazars which will unravel 144 the origin and nature of their variability (und den zugrunde liegen 145 Beschleunigungsmachanismen der kosmischen Strahlung). The telescope 146 design is based on a technological upgrade of one of the former 147 telescopes of the HEGRA collaboration still located at the Observatorio 148 Roque de los Muchachos on the Canarian Island La Palma (Spain). With 149 the upgrade an improvement in senitivity by 25\%{\bf (?)} and a lower 150 energy threshold in the order of 350\,GeV{\bf (?)} will be achieved. 151 152 {\bf IceCube erw"ahnen?} 153 {\em Nicht gescheduled von anderen IACTs?} 154 155 {\em 144 We propose to set up a robotic imaging air Cherenkov telescope with low 145 cost, but high performance design for remote operation. The goal is to 146 dedicate this gamma-ray telescope to long-term monitoring observations 147 of nearby, bright blazars at very high energies. We will (i) search for 148 orbital modulation of the blazar emission due to supermassive black 149 hole binaries, (ii) study the statistics of flares and their physical 150 origin, and (iii) correlate the data with corresponding data from the 151 neutrino observatory IceCube to search for evidence of hadronic 152 emission processes. The observations will also trigger follow-up 153 observations of flares with higher sensitivity telescopes such as 154 MAGIC, VERITAS, and H.E.S.S.\ Joint observations with the Whipple 155 monitoring telescope will start a future 24h-monitoring of selected 156 sources with a distributed network of robotic telescopes. The telescope 157 design is based on a full technological upgrade of one of the former 158 telescopes of the HEGRA collaboration (CT3) still located at the 159 Observatorio Roque de los Muchachos on the Canarian Island La Palma 160 (Spain). After this upgrade, the telescope will be operated 161 robotically, a much lower energy threshold below 350\,GeV will be 162 achieved and the observation time required for gaining the same signal 163 as with CT3 will be reduced by a factor of 6. 164 165 Unser Vorhaben besteht darin, ein robotisches Luft-Cherenkov-Teleskop 166 mit geringen Kosten aber hoher Leistung fernsteuerbar in Betrieb zu 167 nehmen. Das Ziel ist es, dieses gamma-ray Teleskop ganz der 168 Langzeitbeobachtung von nahen, hellen Blazaren bei sehr hohen Energien 169 zu widmen. Wir werden (i) nach Modulationen der Blazar-Emission durch 170 Bin"arsysteme von supermassiven Schwarzen L"ochern suchen, (ii) die 171 Statistik von gamma-Ausbr"uchen und deren physikalischen Ursprung 172 untersuchen und (iii) die Daten mit entsprechenden Daten von dem 173 Neutrino-Telskop IceCube korrelieren, um Nachweise f"ur hadronische 174 Emissionsprozesse zu finden. Die Beobachtungen werden zus"atzlich 175 Nachfolgebeobachtungen von gamma-Ausbr"uchen mit h"ohersensitiven 176 Teleskopen wie MAGIC, VERITAS und H.E.S.S.\ triggern. Auf einander 177 abgestimmte Beobachtungen zusammen mit dem Whipple Teleskop werden der 178 Auftakt zu einer zuk"unftigen 24-Stunden-Beobachtung von selektierten 179 Quellen mit einem verteilten Netzwerk robotischer Cherenkov-Teleskope 180 sein. Das Teleskop-Design basiert auf einem kompletten technologischen 181 Upgrade eines der Teleskope der fr"uheren HEGRA-Kollaboration, welches 182 noch immer am Observatorio Roque de los Muchachos auf der kanarischen 183 Insel La Palma (Spanien) gelegen ist. Nach diesem Upgrade wird das 184 Teleskop robotisch betrieben werden und eine wesentlich geringere 185 Energieschwelle von unter 350\,GeV aufweisen, w"ahrend gleichzeitig die 186 notwendige Beobachtungszeit, um dasselbe Signal wie CT3 zu erhalten, um 187 einen Faktor 6 verringert wird. 188 189 \newpage 190 191 \section[2]{Stand der Forschung, eigene Vorarbeiten\\Science case, preliminary work by proposer} 192 193 \subsection[2.1]{Science case (Stand der Forschung)} 194 195 Since the termination of the HEGRA observations, the succeeding 196 experiments MAGIC and H.E.S.S. have impressively extended the physical 197 scope of gamma ray astronomy detecting tens of formerly unknown gamma 198 ray sources and analyzing their energy spectra, morphology, and 199 temporal behavior. This became possible by lowering the energy 200 threshold from 700\,GeV to less than 100\,GeV and increasing at the same 201 time the sensitivity by a factor of five. A diversity of astrophysical 202 source types such as pulsar wind nebulae, supernova remnants, 203 microquasars, pulsars, radio galaxies, clusters of galaxies, gamma ray 204 bursts and blazars have been studied with these telescopes. 205 206 The main class of extragalactic, very high energy gamma-rays sources 207 detected with imaging air-Cherenkov telescopes are blazars, i.e. 208 accreting supermassive black holes exhibiting a relativistic jet that 209 is closely aligned with the line of sight. The non-thermal blazar 210 spectrum covers up to 20 orders of magnitude in energy, from 211 long-wavelength radio waves to multi-TeV gamma-rays. In addition, 212 blazars are characterized by rapid variability, high degrees of 213 polarization, and super-luminal motion of knots in their 214 high-resolution radio images. The observed behavior can readily be 215 explained assuming relativistic bulk motion and in situ particle 216 acceleration, e.g. at shock waves, leading to synchrotron 217 (radio-to-x-ray) and self-Compton (gamma-ray) emission \citep{Blandford}. 218 Additionally, inverse Compton scattering of external photons may play a 219 role in producing the observed gamma rays \citep{Dermer,Begelman}. 220 Variability may hold the key to understanding the details of the 221 emission processes and the source geometry, and the development of 222 time-dependent models is currently on the agenda of model builders 223 worldwide. 224 225 Although particle acceleration inevitably affects electrons and protons 226 (ions), the electrons are commonly believed to be responsible for 227 producing the observed emission owing to their lower mass and thus much 228 stronger energy losses (at the same energy). The relativistic protons, 229 which could either originate from the accretion flow or from entrained 230 ambient matter, will quickly dominate the momentum flow of the jet. 231 This {\em baryon pollution} has been suggested to solve the energy 232 transport problem in gamma ray bursts, and is probably present in 233 blazar jets as well, even if they originate as pair jets in a black 234 hole ergosphere\citep{Meszaros}. Protons and ions accelerated in the 235 jets of blazars can reach extremely high energies before energy losses 236 become important \citep{Mannheim:1993}. Escaping particles contribute 237 to the observed flux of ultrahigh energy cosmic rays in a major way. 238 Blazars and their unbeamed hosts, the radio galaxies, are thus the 239 prime candidates for origin of ultrahigh energy cosmic rays 240 \citep{Rachen}, and this can be investigated with the IceCube and AUGER 241 experiments. Recent results of the AUGER experiment show a significant 242 anisotropy of the highest energy cosmic rays and point at either nearby 243 AGN or sources with a similar spacial distribution as their origin 244 \citep{AUGER-AGN}. 245 246 In some flares, a large ratio of the gamma-ray to optical luminosity is 247 observed. This is difficult to reconcile with the primary leptonic 248 origin of the emission, since the accelerated electron pressure would 249 largely exceed the magnetic field pressure. For shock acceleration to 250 work efficiently, particles must be confined by the magnetic field for 251 a time longer than the cooling time. The problem vanishes in the 252 following model: Photo-hadronic interactions of accelerated protons and 253 synchrotron photons induce electromagnetic cascades, which in turn 254 produce secondary electrons causing high energy synchrotron 255 gamma-radiation. This demands much stronger magnetic fields in line 256 with magnetic confinement \citep{Mannheim:1995}. Short variability time 257 scales can result from dynamical changes of the emission zone, running 258 e.g. through an inhomogeneous environment. 259 260 The contemporaneous spectral energy distributions for hadronic and 261 leptonic models bear many similarities, but also marked differences, 262 such as multiple bumps which are possible even in a one-zone hadronic 263 model \citep{Mannheim:1999}. These properties allow conclusions 264 about the accelerated particles. Noteworthy, even for nearby blazars 265 the spectrum must be corrected for attenuation of the gamma rays due to 266 pair production in collisions with low-energy photons from the 267 extragalactic background radiation field \citep{Kneiske}. 268 Ultimately, the hadronic origin of the emission must be probed with 269 correlated gamma-ray and neutrino observations, since the pion decay 270 initiating the cascades involves a fixed ratio of electron-positron 271 pairs, gamma-rays, and neutrinos. A dedicated monitoring campaign 272 jointly with IceCube has the best chance for success. Pilot studies 273 done with MAGIC and IceCube indicate that the investigation of neutrino 274 event triggered gamma-ray observations are statistically 275 inconclusive \citep{Leier:2006}. 276 277 The variability time scale of blazars ranges from minutes to months, 278 generally showing the largest amplitudes and the shortest time scales 279 at the highest energies. Recently, a doubling time scale of two minutes 280 has been observed in a flare of Mrk\,501 with the MAGIC 281 telescope \citep{Albert:501}. A giant flare of PKS\,2155-304 discovered by 282 H.E.S.S.\ \citep{Aharonian:2007pks} has shown similarly short 283 doubling time scales and a flux of up to 16 times the flux of the Crab 284 Nebula. Indications for TeV flares without evidence for an accompanying 285 x-ray flare, coined orphan flares, have been observed, questioning the 286 synchrotron-self-Compton mechanism being responsible for the 287 gamma-rays. Model ramifications involving several emission components, 288 external seed photons, or hadronically induced emission may solve the 289 problem \citep{Blazejowski}. Certainly, the database for contemporaneous 290 multi-wavelength observations is still far from proving the 291 synchrotron-self-Compton model. 292 293 Generally, observations of flares are prompted by optical or x-ray 294 alerts, leading to a strong selection bias. The variability presumably 295 reflects the non-steady feeding of the jets and the changing interplay 296 between particle acceleration and cooling. In this situation, 297 perturbations of the electron density or the bulk plasma velocity are 298 traveling down the jet. The variability could also reflect the changing 299 conditions of the external medium to which the jet flow adapts during 300 its passage through it. In fact, a clumpy, highly inhomogeneous 301 external medium is typical for active galactic nuclei, as indicated by 302 their clumpy emission line regions, if visible against the 303 Doppler-enhanced blazar emission. Often the jets bend with a large 304 angle indicating shocks resulting from reflections off intervening 305 high-density clouds. Changes in the direction of the jet flow lead to 306 large flux variations due to differential Doppler boosting. 307 308 Helical trajectories, as seen in high-resolution radio maps resulting 309 from the orbital modulation of the jet base in supermassive black hole 310 binaries, would lead to periodic variability on time scales of months 311 to years \citep{Rieger:2007}. Binaries are expected to be the most 312 common outcome of the repeated mergers of galaxies which have 313 originally built up the blazar host galaxy. Each progenitor galaxy 314 brings its own supermassive black hole as expected from the 315 Magorrian-Kormendy relations. It is subject to stellar dynamical 316 evolution in the core of the merger galaxy, of which only one pair of 317 black holes is expected to survive near the center of gravity. 318 Supermassive black hole binaries close to coalescence are thus expected 319 to be generic in blazars. Angular momentum transport by collective 320 stellar dynamical processes is efficient to bring them to distances 321 close to where the emission of gravitational waves begins to dominate 322 their further evolution until coalescence. Their expected gravitational 323 wave luminosity is spectacularly high, even long before final 324 coalescence and the frequencies are favorable for the detectors under 325 consideration (LISA). Detection of gravitational waves relies on exact 326 templates to filter out the signals and the templates can be computed 327 from astrophysical constraints on the orbits and masses of the black 328 holes. TeV gamma-rays, showing the shortest variability time scales, 329 probe deepest into the jet and are thus the most sensitive probe of the 330 orbital modulation at the jet base. Relativistic aberration is helpful 331 in bringing down the observed periods to below the time scale of years. 332 A tentative hint for a 23-day periodicity of the TeV emission from 333 Mrk\,501 during a phase of high activity in 1997 was reported by 334 HEGRA \citep{Kranich}, and was later confirmed including x-ray and 335 Teleacope Array data \citep{Osone}. The observations can be explained in 336 a supermassive black hole binary scenario \citep{Rieger:2000}. 337 Indications for helical trajectories and periodic modulation of optical 338 and radio lightcurves on time scales of tens of years have also been 339 described in the literature (e.g. \cite{Hong,Merrit}). 340 341 To overcome the limitations of biased sampling, a complete monitoring 342 database for a few representative bright sources needs to be obtained. 343 Space missions with all-sky observations at lower photon energies, such 344 as GLAST, GRIPS, or eROSITA, will provide significant multi-wavelength 345 exposure simultaneous to the VHE observations, and this is a new 346 qualitative step for blazar research. For the same reasons, the VERITAS 347 Collaboration keeps the former Whipple telescope alive, albeit its 348 performance seems to have strongly degraded. It is obvious that the 349 large Cherenkov telescopes such as MAGIC, H.E.S.S.\ or VERITAS are mainly 350 used to discover new sources at the sensitivity limit. Thus they will 351 not perform monitoring observations of bright sources with complete 352 sampling during their visibility. However, these telescopes will be 353 triggered by monitoring telescopes and thus improve the described 354 investigations. In turn, operating a smaller but robotic telescope is 355 an essential and cost-effective contribution to the plans for 356 next-generation instruments in ground-based gamma-ray astronomy. 357 Know-how for the operation of future networks of robotic Cherenkov 358 telescopes, e.g. a monitoring array around the globe or a single-place 359 array like CTA, is certainly needed given the high operating shift 360 demands of the current installations. 361 362 In summary, there are strong reasons to make an effort for the 363 continuous monitoring of the few exceptionally bright blazars. This can 364 be achieved by operating a dedicated monitoring telescope of the 365 HEGRA-type, referred to in the following as DWARF (Dedicated 366 multiWavelength Agn Research Facility). Its robotic design will keep 367 the demands on personal and infrastructure on the low side, rendering 368 it compatible with the resources of University groups. The approach is 369 also optimal to educate students in the strongly expanding field of 370 astroparticle physics. 371 372 Assuming conservatively the performance of a single HEGRA-type 373 telescope, long-term monitoring of at least the following blazars is 374 possible: Mrk\,421, Mrk\,501, 1ES\,2344+514, 1ES\,1959+650, 375 H\,1426+428, PKS\,2155-304. We emphasize that DWARF will run as a 376 facility dedicated to these targets only, providing a maximum 377 observation time for the program. Utilizing recent developments, such 378 as improvements of the light collection efficiency due to an improved 379 mirror reflectivity and a better PM quantum efficiency, a 30\% 380 improvement in sensitivity and a lower energy-threshold is reasonable. 381 Current studies show that with a good timing resolution (2\,GHz) a 382 further 50\% increase in sensitivity (compared to a 300\,MHz system) is 383 feasible. Together with an extended mirror area and a large camera, a 384 sensitivity improvement compared to a single HEGRA telescope of a 385 factor of 2.5 and an energy threshold below 350\,GeV is possible. 386 387 \subsection[2.2]{Preliminary work by proposers (Eigene Vorarbeiten)} 388 389 From the experience with the construction, operation and data analysis 390 of Amanda, IceCube, HEGRA and MAGIC the proposing groups contribute the 391 necessary knowledge and experience to build and operate a small imaging 392 air Cherenkov telescope. 393 394 \paragraph{Hardware} 395 396 The Dortmund group is working on experimental and phenomenological 397 astroparticle physics. In the past, the following hardware components 398 were successfully developed: a Flash-ADC based DAQ (TWR, transient 399 waveform recorder), currently in operation for data acquisition in the 400 AMANDA subdetector within the IceCube telescope \citep{Wagner:PhD}, an 401 online software Trigger for the TWR-DAQ system \citep{Messarius:PhD}, 402 online data compression mechanisms (TWR DAQ) \citep{Refflinghaus:Dipl}, 403 monitoring software for the TWR-DAQ-data \citep{Dreyer:Dipl} and 404 in-ice-HV-power-supply for IceCube. This development was done with the 405 companies CAEN, Pisa, Italy and Iseg, Rossendorf, Germany. The HV 406 modules were long time tested under different temperature conditions 407 connected to operating photomultipliers \citep{Bartelt:Dipl}. Prototypes 408 for the scintillator counters of the planned Air Shower Array {\em 409 SkyView} were developed and operated for two years \citep{Deeg:Dipl}. 410 Members of the group (engineers) were involved in the fast trigger 411 development for H1 and are involved in the FPGA-programming for the 412 LHCb data read out. The group may further use the well equipped 413 mechanical and electronic workshops in Dortmund and the electronic 414 development departure of the faculty. 415 416 The ultra fast drive system of the MAGIC telscopes, suitable for fast 417 repositioning in case of Gamma-Ray Bursts, has been developed, 418 commissioned and programmed by the W"urzburg group 419 \citep{Bretz:2003drive,Bretz:2005drive}. To correct for axis 420 misalignments and possible deformations of the structure (e.g.\ bending 421 of camera holding masts), a pointing correction algorithm was developed 422 \citep{Dorner:Diploma}. Its calibration is done by measurement of the 423 reflection of bright guide stars on the camera surface and ensures a 424 pointing accuracy well below the pixel diameter. Hardware and software 425 (CCD readout, image processing and pointing correction algorithms) have 426 also been developed and are in operation successfully since more than 427 three years \citep{Riegel:2005icrc2}. 428 429 Mirror structures made of plastic material have been developed as 430 Winston Cones for balloon flight experiments previously by the group of 431 Wolfgang Dr"oge. W"urzburg has also participated in the development of 432 a HPD test bench, which has been setup in Munich and W"urzburg. With 433 this setup, HPDs for future improvement of the sensitivity of the MAGIC 434 camera are investigated. 435 436 \paragraph{Software} 437 438 The W"urzburg group has developed a full MAGIC analysis package, 439 flexible and modular enough to easily process DWARF data 440 \citep{Bretz:2005paris,Riegel:2005icrc,Bretz:2005mars}. A method for 441 absolute light calibration of the PMs based on Muon images has been 442 adapted and further improved for the MAGIC telescope 443 \citep{Meyer:Diploma,Goebel:2005}. Both, data analysis and Monte Carlo 444 production, have been fully automatized, such that both can run with 445 sparse user interaction \citep{Dorner:2005icrc}. The analysis was 446 developed to be powerful and as robust as possible to be best suited 447 for automatic processing \citep{Dorner:2005paris}. Experience with 448 large amount of data (up to 15\,TB/month) has been gained over five 449 years now. The datacenter is equipped with a professional multi-stage 450 (hierarchical) storage system. Two operators are paid by the physics 451 faculty. Currently efforts in W"urzburg and Dortmund are ongoing to 452 turn the old inflexible Monte Carlo programs, used by the MAGIC 453 collaboration, into modular packages which allows easy simulation of 454 other setups. Experience with Monte Carlo simulations, especially 455 CORSIKA, is contributed by the Dortmund group, which has actively 456 implemented changes into the CORSIKA program, such as an extension to 457 large zenith angles, prompt meson production and a new atmospheric 458 model \citep{Haffke:Dipl,Schroeder:PhD} for the local atmosphere of La 459 Palma. Furthermore the group has developed high precision Monte Carlos 460 for Lepton propagation in different media \citep{hepph0407075}. An 461 energy unfolding method and program has been adapted for IceCube and 462 MAGIC data analysis \citep{Curtef:CM,Muenich:ICRC}. 463 464 \paragraph{Phenomenology} 465 466 Both groups further have experience with source models and theoretical 467 computations of gamma ray and neutrino spectra expected from blazars. 468 The relation between the two messengers is a prime focus of interest. 469 Experience with corresponding multi-messenger data analyses involving 470 MAGIC and IceCube data is available in the Dortmund group. Research 471 activities are also related with relativistic particle acceleration 472 \citep{Meli} and gamma ray attenuation \citep{Kneiske}. The W"urzburg 473 group has organized and carried out multi-wavelength observations of 474 bright blazars involving MAGIC, Suzaku, the IRAM telescopes, and the 475 optical KVA telescope \citep{Ruegamer}. Signatures of supermassive 476 black hole binaries, which are most relevant also for gravitational 477 wave detectors, are investigated jointly with the German LISA 478 consortium (Burkart, Elbracht ongoing research, funded by DLR). 479 Secondary gamma rays due to dark matter annihilation events are 480 investigated both from their particle physics and astrophysics aspects. 481 Another main focus of research is on models of radiation and particle 482 acceleration processes in blazar jets (hadronic and leptonic models), 483 leading to predictions of correlated neutrino emission \citep{Rueger}. 484 This includes simulations of particle acceleration due to the Weibel 485 instability \citep{Burkart}. Much of this research at W"urzburg is 486 carried out in the context of the research training school GRK\,1147 487 {\em Theoretical Astrophysics and Particle Physics}. 488 489 \section[3]{Ziele/Goals} 490 491 \subsection[3.1]{Ziele/Goals} 492 493 The aim of the project is to put the former CT3 of the HEGRA 494 collaboration on the Roque de los Muchachos back into operation - with 495 an enlarged mirror surface, a new camera with higher quantum 496 efficiency, and new fast data acquisition system, under the name of 497 DWARF. The energy threshold will be lowered, and the sensitivity of 498 DWARF will be greatly improved compared to HEGRA CT3 ({\bf see plot 499 xxx/at the end}). Commissioning and the first year of data taking 500 should be carried out within the three years of the requested funding 501 period. 502 503 \begin{figure}[ht] 504 \begin{center} 505 \includegraphics*[width=0.495\textwidth,angle=0,clip]{CT3.eps} 506 \includegraphics*[width=0.495\textwidth,angle=0,clip]{DWARF.eps} 507 \caption{Left: xxxxx Right: yyyy} 508 \label{CT3} 509 \label{DWARF} 510 \end{center} 511 \end{figure} 512 513 The telescope will be operated robotically to reduce costs and man 514 power demands. Furthermore, we seek to obtain know-how for the 515 operation of future networks of robotic Cherenkov telescopes (e.g. a 516 monitoring array around the globe or CTA) or telescopes at inaccessible 517 sites. From the experience with the construction and operation of MAGIC 518 or HEGRA, the proposing groups consider the planned focused approach 519 (small number of experienced scientists) as optimal for achieving the 520 project goals. The available automatic analysis package developed by 521 the W"urzburg group for MAGIC is modular and flexible, and can thus be 522 used with minor changes for the DWARF project. 523 524 \begin{figure}[htb] 525 \begin{center} 526 \includegraphics*[width=0.8\textwidth,angle=0,clip]{visibility.eps} 527 \caption{blablbaaaa} 528 \label{visibility} 529 \end{center} 530 \end{figure} 531 532 %[[Image:dwarf-source-visibility.png|thumb|300px|Source visibility ([[Media:dwarf-source-visibility.eps|eps]])]] 533 534 The scientific focus of the project will be on the long-term monitoring 535 of bright, nearby VHE emitting blazars.

This became possible by 188 lowering the energy threshold from 700\,GeV to less than 100\,GeV and 189 increasing at the same time the sensitivity by a factor of five. 190 191 To fully exploit the discovery potential of the improved sensitivity, 192 the discovery of new, faint objects has become the major task for the 193 new telescopes. A diversity of astrophysical source types such as 194 pulsar wind nebulae, supernova remnants, microquasars, pulsars, radio 195 galaxies, clusters of galaxies, gamma ray bursts, and blazers can be 196 studied with these telescopes and limits their availability for 197 monitoring purposes of well-known bright sources. 198 199 There are strong reasons to make an effort for the continuous 200 monitoring of the few exceptionally bright blazars. This can be 201 achieved by operating a dedicated monitoring telescope of the 202 HEGRA-type, referred to in the following as DWARF (Dedicated 203 multiWavelength Agn Research Facility). The reasons are outlined in 204 detail below. 205 206 \textbf{The science case:} The variability of blazars, seen across the 207 entire electromagnetic spectrum, arises from the dynamics of 208 relativistic jets and the particle acceleration going on in them. The 209 jets are launched from the vicinity of accreting supermassive black 210 holes, and theoretical models predict variability arising from the 211 interplay between jet expansion, particle injection, acceleration and 212 cooling.\\ 213 214 Long-term monitor observations of bright blazars are the key to obtain 215 a solid and complete data base for variability investigations. 216 217 {\bf Hier sollte ganz klar rauskommen was der aktuelle Stand der 218 Forschung ist und wieso man um weiter zu kommen unbedingt ein 219 long-term monitoring IACT braucht} 220 221 {\bf Geigermode APDs?} 222 223 \subsubsection{High energy gamma and neutrino sources} 224 225 {\bf Aus den folgenden beiden Abschnitten kann man vielleicht einen 226 (k"urzeren) machen?} 227 228 The TeV photon astronomy succeeded in discovering {\bf 14} 229 extragalactic and {\bf ???} galactic objects at the sky during the past 230 decades. Additionally there are two diffuse regions within our galaxy 231 which have been detected by H.E.S.S.\cite{Aharonian:2006} and Milagro 232 \cite{Milagro:2007}. 233 %The first source was discovered in the 234 %year 19{\bf??} by the {\bf HEGRA} collaboration {\it (War das nicht wer 235 %anders, die zu allererst den Crab sahen?...ZITAT?)}. 236 In comparison to 237 x-ray measurments, which are able to scan the entire sky for sources 238 and thus have cataloged more than {\bf 1000 ???} sources, this number 239 appears to be quite small. One reason for this is the small field of 240 view of imaging air cherenkov telesopes (IACTs), another reason the 241 absorption of the TeV photon signal of distant ($z>0.2$) sources due to 242 extragalactic background light (EBL). Due to this small statistic at 243 the moment it is of particular importance that instruments with high 244 sensitivity concentrate on the observation of new objects in the TeV sky 245 and not on the quantitative, permanent observation of already known 246 sources. 247 % BRAUCHT MAN DEN FOLGENDEN ABSATZ WIRKLICH 248 %Even when a source was observed over a longer period of time 249 %this does mean {\bf less than three month ???? {\it Viel l"anger sind 250 %die Quellen am St"uck doch gar nicht sichtbar, oder? Sinnvoller w"are 251 %es wom"oglich die wenigen Beobachtungsstunden in diesen X Monaten 252 %hervorzuheben.}} But one has to take into account that during this time 253 %also periods of bad weather and times with strong moon light can 254 %significantly reduce observation time. Furthermore one has to consider 255 %that the sources are visible in the sky only for a few hours each night. 256 257 %{\bf Ist die Aufz"ahlung nich total "ubertrieben? Ist es f"ur unseren 258 %Antrag wirklich interessant welchem Typ die detektierten AGN angeh"oren 259 %und wie sie hei"sen?} 260 261 The so far observed galactic objects are microqasars and supernova 262 remnands (SNR). The identified extragalactic sources are active 263 galactic nuclei (AGN). 264 %NOETIG??? The objects are listed in table~\ref{dummy} {\bf 265 %TESHIMAS VORTRAG IN MADISON}. 266 The AGN are 13 BLLacs and one FR-I 267 galaxy, M87. So High-peaked BL Lacertae objects are the prime source 268 population for studies with Cherenkov telescopes. It is obvious that 269 monitoring observations of strong blazars are orthogonal to the mission 270 of the larger Cherenkov telescopes with their discovery potential for 271 new sources (luminosity function, redshift distribution). 272 {\bf Das hatten wir oben eigtnlich schonmal} 273 274 In case of hadronic particle acceleration within the TeV emitters, the 275 signal may arise from $\pi^0$-decays. These neutral pions are decay 276 products of delta resonances, which are formed in proton-photon 277 interactions. Another decay channel of the delta resonance leads to the 278 production of charged pions and thus to neutrino production, coincident 279 with the TeV photons. Therefrom TeV sources are always 280 interesting objects for investigations with high energy neutrino 281 telescopes. 282 283 The strong variability in the temporal evolution of the AGN TeV photon 284 spectra cannot be explained conclusively yet, {\it warum braucht man 285 f"ur die Untersuchung Langzeitbeobachtungen?} 286 287 {\bf SENSITIVIT\"ATSPLOT, Was hat der hier zu suchen?, Aber irgendwo muessen 288 wir noch glaubhaft machen dass unsere Sensitivit"at ausreicht}\\ 289 {\bf TABELLE QUELLEN, Was bringt das f"ur den Antrag oder den Referee?}\\ 290 {\bf AGN Physik kann man nicht ohne die unteren Paragraphen erkl"aren, 291 Muss man die hier erkl"aren?

The sensitivity above 500\,GeV of this new instrument 417 will thus correspond with the one of the also disused Whipple 418 telescope. \textbf{WHIPPLE wird aber noch benutzt!!!} 419 420 The layout of the telescope shall be carried out modular in such a 421 sense that components of future telescopes (mirror, camera, DAQ) can be 422 tested and optimized at this bodywork. 423 424 %Wissenschaftlich sollen folgende Punkte realisiert werden: 425 With the upgraded instrument the following scientific aims shall be 426 realized: 427 428 \begin{enumerate} 429 \item Long-term observations of temporal variations of TeV gamma 430 ray sources.\\ 431 An understanding of this variability will deepen our knowledge about 432 433 \begin{itemize} 434 \item the composition and generation of the jets, intimately connected 435 to the physics of the ergosphere of rapidly spinning black holes 436 embedded into the hot plasma from the accretion flow. 437 \item the plasma physics responsible for highly efficient particle 438 acceleration, bearing similarities to plasma physics of the interaction 439 between extremely intense laser beams and matter. 440 \item {the orbital modulation of jets due to binary black holes 441 expected from galaxy merger models.\\ \textbf{the search for signatures of 442 binary black hole systems from orbital modulation of VHE gamma ray 443 emission} \cite{Rieger:2000, Rieger:2001}\\ 444 \item {\bf Wird das nicht ein bisschen viel Rieger? 445 \item Rieger; Periodic variability and binary black hole systems in blazars 446 \item Rieger; Supermassive binary black holes among cosmic gamma-ray sources 447 \item Rieger; On the geometric origin of periodicity in blazar-type sources 448 }} 449 \end{itemize} 450 451 Long-term monitor observations of bright blazars are the key to obtain 452 a solid data base for variability investigations.

For calibration purposes, some time will be 490 scheduled for observations of the Crab nebula, which is the brightest 491 known VHE emitter with constant flux.\\ 492 493 In detail the following investigations are planned: 494 \begin{itemize} 495 \item As direct result of the measurements, the duty cycle, the 496 baseline emission, and the power spectrum of flux variations will be 497 determined and compared with variability properties in other wavelength 498 ranges. 499 500 \item The lightcurves will be interpreted using models for the 501 nonthermal emission from relativistically expanding plasma jets. In 502 particular models currently developed in the context of the Research 503 Training Group "Theoretical Astrophysics" in W"urzburg 504 (Graduiertenkolleg, GK1147) shall be used. Particle acceleration is 505 studied with hybrid MHD and particle-in-cell methods. 506 507 \item The black hole mass and accretion rate will be determined from 508 the emission models. Estimates of the black hole mass from emission 509 models, a possible orbital modulation, and the Magorrian relation 510 (relating the black hole mass with the stellar bulge mass of the host 511 galaxy) will be compared. \cite{Rieger:2003} {\bf eigentlich ist das 512 nicht mehr die Stelle mit Zitaten sondern die wo wir sagen, dass 513 wir das Know-how - in Form von Frank - haben.} 514 515 \item \textbf{To achieve a maximal database for these studies the 516 observation schedule will be arranged together with the one for 517 Whipple. (Letter of support?) ($\rightarrow$ collaboration with 518 Veritas)} 519 520 \item When flaring states will be discovered during the monitor 521 program, MAGIC will issue a Target of Opportunity observation to obtain 522 better time resolution (Letters of support?). Corresponding 540 \item to determine the duty cycle, the baseline emission, and the power 541 spectrum of flux variations. 542 \item to cooperate with the Whipple monitoring telescope for an 543 extended time coverage. 544 \item to prompt Target of Opportunity (ToO) observations with MAGIC in 545 the case of flares increasing time resolution. Corresponding 523 546 Target-of-Opportunity (ToO) proposals to H.E.S.S.\ and Veritas are in 524 547 preparation. 525 526 \item DWARF observations will be combined with simultaneous MAGIC 527 observations. By this kind of observation the energy range of the MAGIC 528 telescope can be stretched to higher energies. This in turn leads to 529 the so far unique possibility to cover an energy range of tens of GeV 530 to several tens of TeV at the same time allowing the study of the 531 inverse compton peaks as well as absorption due to EBL simultaneously. 532 By a software coincidence trigger the sensitivity in the overlapping 533 energy region might be improved further. 534 535 \item Correlating the arrival times of neutrinos detected by the 536 neutrino telescope IceCube with simultaneous measurements of DWARF will 537 allow to test the hypothesis that flares in blazar jets are connected 538 to hadronic emission processes and thus to neutrino emission from these 539 sources. The investigation proposed here is complete for both, neutrino 540 and gamma observations, and can therefore lead to conclusive results. 541 542 \item The diffusive fluxes of escaping UHE cosmic rays obtained from 543 AUGER or flux limits of neutrinos from IceCube, respectively, will be 544 used to constrain models of UHE cosmic ray origin and large-scale 545 magnetic fields. 546 547 \item Multi-frequency observations together with the Mets"ahovi Radio 548 Observatory and the optical Tuorla Observatory are planned (Letters of 549 support appendix). The measurements will be correlated with INTEGRAL 550 and GLAST results, when available. X-ray monitoring using the SWIFT and 551 Suzaku facilities will be proposed. 552 553 \item The most ambitious scientific goal of this proposal is the search 554 for signatures of binary black hole systems from orbital modulation of 555 VHE gamma ray emission. In case of a confirmation of the present hints 556 in the temporal behaviour of Mrk501, gravitational wave templates could 557 be computed with high accuracy to establish their discovery with LISA 558 (PhD project at W"urzburg funded by the German LISA consortium). 548 \item to observe simultaneously with MAGIC which will provide an 549 extended bandwidth from below 100\,GeV to multi-TeV energies. 550 \item to obtain multi-frequency observations together with the 551 Mets"ahovi Radio Observatory and the optical Tuorla Observatory 552 (Letters of support appendix). The measurements will be correlated with 553 INTEGRAL and GLAST results, when available. x-ray monitoring using the 554 SWIFT and Suzaku facilities will be proposed. 559 555 \end{itemize} 560 556 561 \textbf{The technical setup:} At the Observatorio de los Muchachos 562 (ORM), at the MAGIC site, the mount of the former HEGRA telescope CT3 563 now owned by the MAGIC collaboration is still operational. One hut for 564 electronics close to the telescope is available. Additional space is 565 available in the MAGIC counting house. The MAGIC Memorandum of 566 Understanding allows for operating it as an auxiliary instrument, and 567 basic support from the shift crew of MAGIC is guaranteed, although 568 robotic operation is the primary goal. Robotic operation is necessary 569 to reduce costs and man power demands. \textbf{Besides it reduces air 570 pollution by significantly reducing traveling.} Furthermore, we seek to obtain 571 know-how for the operation of future networks of Cherenkov telescopes 572 (e.g. a monitoring array around the globe or CTA) or telescopes at 573 inaccessible sites. From the experience with the construction and 574 operation of MAGIC or HEGRA, respectively, the proposing groups 575 consider the planned focused approach (small number of experienced 576 scientists) as optimal for achieving the project goals. The available577 automatic analysis package developed by the W"urzburg group for MAGIC 578 is modular and flexible, and can thus be used with minor changes for 579 the DWARF project. Therefore construction, commissioning and operation 580 of a small scale Cherenkov telescope are best suitable for education 581 and training of students by experienced scientists. 557 Interpretation of the data will yield crucial information about 558 \begin{itemize} 559 \item the nature of the emission processes going on in relativistic 560 jets. We plan to interpret the data with models currently developed in 561 the context of the Research Training Group {\em Theoretical 562 Astrophysics} in W"urzburg (Graduiertenkolleg, GK\,1147), including 563 particle-in-cell and hybrid MHD models. 564 \item the black hole mass and accretion rate fitting the data with 565 emission models. Results will be compared with estimates of the black 566 hole mass from the Magorrian relation. 567 \item the flux of relativistic protons (ions) by correlating the rate 568 of neutrinos detected with the neutrino telescope IceCube and the rate 569 of gamma ray photons detected with DWARF, and thus the rate of escaping 570 cosmic rays. 571 \item the orbital modulation owing to a supermassive binary black hole. 572 Constraints on the binary system will allow to compute most accurate 573 templates of gravitational waves, which is a connected project at 574 W"urzburg in the German LISA consortium funded by DLR. 575 \end{itemize} 576 577 \subsection{Arbeitsprogramm/Work schedule} 582 578 583 579 To complete the mount to a functional Cherenkov telescope within a 584 580 period of one year, the following steps are necessary: 585 581 586 \paragraph{Camera:} 587 For long-term observations stability of the camera is a major 588 criterion. To keep the systematic errors small good background 582 The work schedule assumes that the work will begin in January 2008, 583 immediately after funding. Later funding would accordingly shift the 584 schedule. Each year is divided into quarters (see figure xxx). 585 586 \paragraph{Software} 587 \begin{itemize} 588 \item MC adaption (Do/Wue): Due to the large similarities with the MAGIC telescope, within half a year new Monte Carlo code can be programmed using parts of the existing MAGIC Monte Carlo code. For tests and cross-checks another period of six months is necessary. 589 \item Analysis adaption (Wue): The modular concept of the Magic Analysis and Reconstruction Software (MARS) allows a very fast adaption of the telescope setup, camera and data acquisition properties within half a year. 590 \item Adaption Drive software (Wue): Since the new drive electronics will be based on the design of the MAGIC II drive system the control software can be reused unchanged. The integration into the new slow control system will take about half a year. It has to be finished at the time of arrival of the drive system components in 2009/1. 591 \item Slow control/DAQ (Do): A new data acquisition and slow control system for camera and auxiliary systems has to be developed. Based on experiences with the AMANDA DAQ, the Domino DAQ developed for MAGIC II will be adapted and the slow control integrated within three quarters of a year. Commissioning will take place with the full system in 2009/3. 592 \end{itemize} 593 594 \paragraph{Mirrors (Wue)} First prototypes for the mirrors are already available. After testing (six months), the production will start in summer 2008 and shipment will be finished before the full system assembly 2009/2. 595 \paragraph{Drive (Wue)} After a planning phase of half a year to simplify the MAGIC II drive system for a smaller telescope (together with the delivering company), ordering, production and shipment should be finished in 2009/1. The MAGIC I and II drive systems have been planned and implemented successfully by the Wuerzburg group. 596 \paragraph{Auxiliary (Wue)} Before the final setup in 2009/1, all auxiliary systems (weather station, computers, etc.) will have been specified, ordered and shipped. 597 \paragraph{Camera (Do)} The camera has to be ready six month after the shipment of the other mechanical parts of the telescope. For this purpose camera tests have to take place in 2009/2, which requires the assembly of the camera within six months before. By now, a PM test bench which allows to finish planning and ordering of the camera parts and PMs until summer 2008, before the construction begins, is set up in Dortmund. In addition to the manpower permanently provided by Dortmund for production and commissioning, two engineers will participate in the construction phase. 598 \paragraph{Full System (Do/Wue)} The full system will be assembled after delivering of all parts in the beginning of spring 2009. Start of the commissioning is planned four months later. First light is expected in autumn 2009. This would allow an immediate full system test with a well measured, strong and steady source (CrabNebula). After the commissioning phase will have been finished in spring 2010, full robotic operation will be provided. 599 600 Based on the experience with setting up the MAGIC telescope we estimate 601 this workschedule as conservative. 602 603 \subsubsection[3.3]{Experiments with humans (Untersuchungen am Menschen)} 604 none 605 \subsubsection[3.4]{Experiments with animals (Tierversuche)} 606 none 607 \subsubsection[3.5]{Experiments with recombinant DNA (Gentechnologische Experimente)} 608 none 609 610 \section[4]{Beantragte Mittel/Funds requested} 611 612 We request funding for a total of three years.

To keep the systematic errors small, a good background 589 675 estimation is mandatory. The only possibility for a synchronous 590 676 determination of the background is the determination from the night-sky 591 677 observed in the same field-of-view with the same instrument. To achieve 592 this the observed position is moved out of the camera center which678 this, the observed position is moved out of the camera center which 593 679 allows the estimation of the background from positions symmetric with 594 680 respect to the camera center (so called wobble-mode). This observation 595 mode increases the sensitivity by a factor of two \textbf{$\sqrt{2}$?} because spending 596 observation for dedicated background observations becomes obsolete, 597 which also ensures a better time coverage of the observed sources. 598 Having a camera large enough allowing more than one independent 599 position for background estimation increases sensitivity further by 600 better background statistics. This is the case if the source can be 601 shifted 0.6deg-0.7deg out of the camera center. A camera completely 602 containing shower images of events in the energy region of 1TeV-10TeV 603 should have a diameter in the order of 5 deg. To decrease the 604 dependence of the background measurement on the camera geometry, a 605 camera layout as symmetric as possible will be chosen.
