Upper limit for gamma-ray emission above 140 GeV from the dwarf spheroidal galaxy Draco
MAGIC Collaboration, J. Albert
The nearby dwarf spheroidal galaxy Draco with its high mass to light ratio is one of the most auspicious targets for indirect dark matter searches. Annihilation of hypothetical DM…
The Active Mirror Control of the MAGIC Telescope
A. Biland, M. Garczarczyk, H. Anderhub +4
One of the main design goals of the MAGIC telescopes is the very fast repositioning in case of Gamma Ray Burst (GRB) alarms, implying a low weight of the telescope dish. This is ac…
The Camera of the MAGIC-II Telescope
C. C. Hsu, A. Dettlaff, D. Fink +13
The MAGIC 17m diameter Cherenkov telescope will be upgraded with a second telescope within the year 2007. The camera of MAGIC-II will include several new features compared to the M…
Upgrade of the MAGIC Telescope with a Multiplexed Fiber-Optic 2 GSamples/s FADC Data Acquisition system
MAGIC Collaboration, Florian Goebel, Hendrik Bartko +6
In February 2007 the MAGIC Air Cherenkov Telescope for gamma ray astronomy was fully upgraded with a fast 2 GSamples/s digitization system. The upgraded readout system uses a novel…
Recent progress of GaAsP HPD development for the MAGIC telescope project
T. Y. Saito, M. Shayduk, M. V. Fonseca +6
Today the Hybrid Photon Detector (HPD) is one of the few low light level (LLL) sensors that can provide an excellent single and multiple photoelectron (ph.e.) amplitude resolution.…
SiPM Development for Astroparticle Physics Applications
M. Teshima, B. Dolgoshein, R. Mirzoyan +2
The SiPM is a novel solid state photodetector which can be operated in the single photon counting mode. It has excellent features, such as high quantum efficiency, good charge reso…
Study of the performance and capability of the new ultra-fast 2 GSample/s FADC data acquisition system of the MAGIC telescope
D. Tescaro, H. Bartko, N. Galante +7
In February 2007 the MAGIC Air Cherenkov Telescope for gamma-ray astronomy was fully upgraded with an ultra fast 2 GSamples/s digitization system. Since the Cherenkov light flashes…
The reflecting surface of the MAGIC-II Telescope
D. Bastieri, J. Arnold, C. Baixeras +19
The MAGIC Collaboration is building a second telescope, MAGIC II, improving the design of the current MAGIC Telescope. MAGIC II is being built at 85 m of distance from MAGIC I, and…
The MAGIC Project: Contributions to ICRC 2007
J. Albert, E. Aliu, H. Anderhub +142
The MAGIC Project: Contributions to ICRC 2007, Merida, Mexico. Contents pages for the Contribution on behalf of the MAGIC Collaboration to the 30th ICRC that took place in July 200…
Very High Energy Gamma-ray Radiation from the Stellar-mass Black Hole Cygnus X-1
MAGIC Collaboration, J. Albert
We report on the results from the observations in very high energy band (VHE, E_gamma > 100 GeV) of the black hole X-ray binary (BHXB) Cygnus X-1. The observations were performed w…
Discovery of VHE Gamma Radiation from IC443 with the MAGIC Telescope
MAGIC Collaboration
We report the detection of a new source of very high energy (VHE, E_gamma >= 100GeV) gamma-ray emission located close to the Galactic Plane, MAGIC J0616+225, which is spatially coi…
Systematic search for VHE gamma-ray emission from X-ray bright high-frequency BL Lac objects
M. Meyer
All but three (M87, BL Lac and 3C 279) extragalactic sources detected so far at very high energy (VHE) gamma-rays belong to the class of high-frequency peaked BL Lac (HBL) objects.…
Observation of VHE gamma-rays from Cassiopeia A with the MAGIC telescope
J. Albert
We searched for very high energy (VHE) gamma-ray emission from the supernova remnant Cassiopeia A. The shell-type supernova remnant Cassiopeia A was observed with the 17 meter MAGI…
VHE Gamma-Ray Observation of the Crab Nebula and its Pulsar with the MAGIC telescope
MAGIC Collaboration, J. Albert
We report about very high energy (VHE) gamma-ray observations of the Crab Nebula with the MAGIC telescope. The gamma-ray flux from the nebula was measured between 60 GeV and 9 TeV.…
A method to measure the mirror reflectivity of a prime focus telescope
R. Mirzoyan, M. Garczarczyk, J. Hose +1
We have developed a method to measure the mirror reflectivity of telescopes. While it is relatively easy to measure the local reflectivity of the mirror material, it is not so stra…
Discovery of very high energy gamma-ray emission from the low-frequency peaked BL Lacertae object BL Lacertae
MAGIC Collaboration, J. Albert
The MAGIC collaboration observed BL Lacertae for 22.2 hr during 2005 August to December and for 26 hr during 2006 July to September. The source is the historical prototype and epon…
Constraints on the steady and pulsed very high energy gamma-ray emission from observations of PSR B1951+32/CTB 80 with the MAGIC Telescope
MAGIC Collaboration, J. Albert
We report on very high energy gamma-observations with the MAGIC Telescope of the pulsar PSR B1951+32 and its associated nebula, CTB 80. Our data constrain the cutoff energy of the…
