MAGIC Observations of PG 1553+113 during a Multiwavelength Campaign in July 2006
MAGIC Collaboration, Albert
The active galactic nucleus PG 1553+113 was observed by the MAGIC telescope in July 2006 during a multiwavelength campaign, in which telescopes in the optical, X-ray, and very high…
The June 2008 flare of Markarian 421 from optical to TeV energies
The Agile Collaboration, Webt Collaboration, Magic Collaboration +2
We present optical, X-ray, high energy ( GeV) and very high energy ( GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken betwee…
Improving the performance of the single-dish Cherenkov telescope MAGIC through the use of signal timing
MAGIC Collaboration
The Cherenkov light flashes produced by Extensive Air Showers are very short in time. A high bandwidth and fast digitizing readout, therefore, can minimize the influence of the bac…
The Fermi Gamma Ray Space Telescope discovers the Pulsar in the Young Galactic Supernova-Remnant CTA 1
Fermi LAT Collaboration
Energetic young pulsars and expanding blast waves (supernova remnants, SNRs) are the most visible remains after massive stars, ending their lives, explode in core-collapse supernov…
Upper Limits on the VHE gamma-ray Emission from the Willman 1 Satellite Galaxy with the MAGIC telescope
MAGIC Collaboration, E. Aliu
We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May 2008. No significant…
First bounds on the high-energy emission from isolated Wolf-Rayet binary systems
MAGIC Collaboration, E. Aliu
High-energy gamma-ray emission is theoretically expected to arise in tight binary star systems (with high mass loss and high velocity winds), although the evidence of this relation…
Photon propagation and the VHE gamma-ray spectra of blazars: how transparent is really the Universe?
A. De Angelis, O. Mansutti, M. Persic +1
Recent findings by gamma-ray Cherenkov telescopes suggest a higher transparency of the Universe to very-high-energy (VHE) photons than expected from current models of the Extragala…
Very High Energy Gamma-Ray Observations of a Strong Flaring Activity in M87 in 2008 February
MAGIC Collaboration, J. Albert
M87 is the only known non blazar radio galaxy to emit very high energy (VHE) gamma-rays. During a monitoring program of M87, a rapid flare in VHE gamma-rays was detected by the MAG…
MAGIC observations of the unidentified TeV gamma-ray source TeV J2032+4130
J. Albert
We observed the first known very high energy (VHE) gamma-ray emitting unidentified source, TeV J2032+4130, for 94 hours with the MAGIC telescope. The source was detected with a sig…
Multi-wavelength (radio, X-ray and gamma-ray) observations of the gamma-ray binary LS I +61 303
MAGIC Collaboration, J. Albert
We present the results of the first multiwavelength observing campaign on the high-mass X-ray binary LS I +61 303 comprising observations at the TeV regime with the MAGIC telescope…
