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…
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…
Detection of very high energy gamma-ray emission from the Perseus cluster head-tail galaxy IC 310 by the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +151
We report on the detection with the MAGIC telescopes of very high energy gamma-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interva…
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…
Magic constraints on Gamma-ray emission from Cygnus X-3
J. Aleksić, L. A. Antonelli, P. Antoranz +156
Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays…
MAGIC observation of the GRB080430 afterglow
MAGIC Collaboration, J. Aleksić, H. Anderhub +151
Context: Gamma-ray bursts are cosmological sources emitting radiation from the gamma-rays to the radio band. Substantial observational efforts have been devoted to the study of gam…
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…
Gamma-ray excess from a stacked sample of high- and intermediate-frequency peaked blazars observed with the MAGIC telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +147
Between 2004 and 2009 a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with a X-ray flux larger than 2 uJy at 1 keV in the redshift range from 0.018 to…
MAGIC TeV Gamma-Ray Observations of Markarian 421 during Multiwavelength Campaigns in 2006
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +145
The Major Atmospheric Gamma Imaging Cerenkov (MAGIC) telescope participated in three multiwavelength (MWL) campaigns, observing the blazar Markarian (Mkn) 421 during the nights of…
