Detection of very-high energy γ-ray emission from NGC 1275 by the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +161
We report on the detection of very-high energy (VHE, E>100 GeV) gamma-ray emission from NGC 1275, the central radio galaxy of the Perseus cluster of galaxies. The source has been d…
Detection of the gamma-ray binary LS I +61 303 in a low flux state at Very High Energy gamma-rays with the MAGIC Telescopes in 2009
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +153
We present very high energy (VHE, E > 100 GeV) γ-ray observations of the γ-ray binary system LS I+61 303 obtained with the MAGIC stereo system between 2009 October and 2010 January…
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…
Environment and properties of emitting electrons in blazar jets: Mrk 421 as a laboratory
Nijil Mankuzhiyil, Stefano Ansoldi, Massimo Persic +1
Here we report our recent study on the spectral energy distribution (SED) of the high frequency BL Lac object Mrk 421 in different luminosity states. We used a full-fledged chi2-mi…
Phase-resolved energy spectra of the Crab Pulsar in the range of 50-400 GeV measured with the MAGIC Telescopes
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +155
We use 73 h of stereoscopic data taken with the MAGIC telescopes to investigate the very high-energy (VHE) gamma-ray emission of the Crab pulsar. Our data show a highly significant…
Observations of the Crab pulsar between 25 GeV and 100 GeV with the MAGIC I telescope
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +156
We report on the observation of -rays above 25\,GeV from the Crab pulsar (PSR B0532+21) using the MAGIC I telescope. Two data sets from observations during the winter period 200…
Mrk 421 active state in 2008: the MAGIC view, simultaneous multi-wavelength observations and SSC model constrained
J. Aleksic, E. A. Alvarez, L. A. Antonelli +150
Context: The blazar Markarian 421 is one of the brightest TeV gamma-ray sources of the northern sky. From December 2007 until June 2008 it was intensively observed in the very high…
The environment and distribution of emitting electrons as a function of source activity in Markarian 421
Nijil Mankuzhiyil, Stefano Ansoldi, Massimo Persic +1
For the high-frequency peaked BL Lac object Mrk 421 we study the variation of the spectral energy distribution (SED) as a function of source activity, from quiescent to active. We…
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…
Searches for Dark Matter annihilation signatures in the Segue 1 satellite galaxy with the MAGIC-I telescope
The MAGIC Collaboration, J. Aleksić, E. A. Alvarez +153
We report the results of the observation of the nearby satellite galaxy Segue 1 performed by the MAGIC-I ground-based gamma-ray telescope between November 2008 and March 2009 for a…
Evidence for an axion-like particle from blazar spectra?
Marco Roncadelli, Alessandro De Angelis, Giorgio Galanti +1
Observations with the Imaging Atmospheric Cherenkov Telescopes H.E.S.S., MAGIC, CANGAROO III and VERITAS have shown that the Universe is more transparent than expected to gamma ray…
High-energy emission from star-forming galaxies
Massimo Persic, Yoel Rephaeli
Adopting the convection-diffusion model for energetic electron and proton propagation, and accounting for all the relevant hadronic and leptonic processes, the steady-state energy…
