FACT - How stable are the silicon photon detectors?
T. Bretz, A. Biland, J. Buß +22
The First G-APD Cherenkov telescope (FACT) is the first telescope using silicon photon detectors (G-APD aka. SiPM). The use of Silicon devices promise a higher photon detection eff…
MAGIC observations of the giant radio galaxy M87 in a low-emission state between 2005 and 2007
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +155
We present the results of a long M87 monitoring campaign in very high energy -rays with the MAGIC-I Cherenkov telescope. We aim to model the persistent non-thermal jet emission…
MAGIC contributions to the 32nd International Cosmic Ray Conference
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +160
Compilation of the papers contributed by the MAGIC collaboration to the 32nd International Cosmic Ray Conference (ICRC 2011), which took place between August 11 and 18, 2011 in Bei…
Constraining Cosmic Rays and Magnetic Fields in the Perseus Galaxy Cluster with TeV observations by the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +161
Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that contribute to a substantial…
The 2010 very high energy gamma-ray flare & 10 years of multi-wavelength observations of M 87
The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
MAGIC discovery of VHE Emission from the FSRQ PKS 1222+21
J. Aleksić, L. Antonelli, P. Antoranz +146
Very High Energy (VHE) gamma-ray emission from the flat spectrum radio quasar (FSRQ) PKS 1222+21 (4C 21.35, z=0.432) was detected with the MAGIC Cherenkov telescopes during a short…
A search for Very High Energy gamma-ray emission from Scorpius X-1 with the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +150
The acceleration of particles up to GeV or higher energies in microquasars has been the subject of considerable theoretical and observational efforts in the past few years. Sco X-1…
Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst
The VERITAS Collaboration, V. A. Acciari, T. Arlen +225
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
FACT -- the First Cherenkov Telescope using a G-APD Camera for TeV Gamma-ray Astronomy (HEAD 2010)
H. Anderhub, M. Backes, A. Biland +33
Geiger-mode Avalanche Photodiodes (G-APD) bear the potential to significantly improve the sensitivity of Imaging Air Cherenkov Telescopes (IACT). We are currently building the Firs…
Observations of the Blazar 3C 66A with the MAGIC Telescopes in Stereoscopic Mode
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +153
We report new observations of the intermediate-frequency peaked BL Lacertae object 3C 66A with the MAGIC telescopes. The data sample we use were taken in 2009 December and 2010 Jan…
MAGIC Upper Limits for two Milagro-detected, Bright Fermi Sources in the Region of SNR G65.1+0.6
J. Aleksić, L. A. Antonelli, P. Antoranz +144
We report on the observation of the region around supernova remnant G65.1+0.6 with the stand-alone MAGIC-I telescope. This region hosts the two bright GeV gamma-ray sources 1FGL J1…
Search for an extended VHE gamma-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +148
Context: Part of the very high energy -ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic background light phot…
A novel camera type for very high energy gamma-ray astronomy based on Geiger-mode avalanche photodiodes
H. Anderhub, M. Backes, A. Biland +28
Geiger-mode avalanche photodiodes (G-APD) are promising new sensors for light detection in atmospheric Cherenkov telescopes. In this paper, the design and commissioning of a 36-pix…
