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…
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…
VHE Gamma-Ray Observation of the Crab Nebula and its Pulsar with the MAGIC telescope
MAGIC Collaboration, J. Albert
We report about very high energy (VHE) gamma-ray observations of the Crab Nebula with the MAGIC telescope. The gamma-ray flux from the nebula was measured between 60 GeV and 9 TeV.…
Discovery of very high energy gamma-ray emission from the low-frequency peaked BL Lacertae object BL Lacertae
MAGIC Collaboration, J. Albert
The MAGIC collaboration observed BL Lacertae for 22.2 hr during 2005 August to December and for 26 hr during 2006 July to September. The source is the historical prototype and epon…
Detection of VHE radiation from the BL Lac PG 1553+113 with the MAGIC telescope
J. Albert et al.
In 2005 and 2006, the MAGIC telescope has observed very high energy gamma-ray emission from the distant BL Lac object PG 1553+113. The overall significance of the signal is 8.8 sig…
