MAGIC upper limits to the VHE gamma-ray flux of 3C454.3 in high emission state
H. Anderhub, S. Vercellone, I. Donnarumma +2
We report upper limits to the very high energy flux (E>100 GeV) of the flat spectrum radio quasar 3C454.3 (z=0.859) derived by the Cherenkov telescope MAGIC during the high states…
Very-High-Energy Gamma Rays from a Distant Quasar: How Transparent Is the Universe?
MAGIC Collaboration, J. Albert
The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar R…
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…
Simultaneous multiwavelength observations of the blazar 1ES1959+650 at a low TeV flux
G. Tagliaferri, L. Foschini, G. Ghisellini +7
We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in May, 2006. Data from the optical, UV, soft- and hard-X-ray and very high energy…
