A luminous and isolated gamma-ray flare from the blazar b2 1215+30
(American Astronomical Society, 2017-02-21)
B2 1215+30 is a BL-Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes and subsequently confirmed by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) ...
Upper limits from five years of blazar observations with the veritas cherenkov telescopes
(American Astronomical Society, 2016-05-18)
Between the beginning of its full-scale scientific operations in 2007 and 2012, the VERITAS Cherenkov telescope array observed more than 130 blazars; of these, 26 were detected as very-high-energy (VHE; E > 100 GeV) ...
Unprecedented study of the broadband emission of mrk 421 during flaring activity in march 2010
(EDP Sciences, 2015-05-27)
Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED).
Aims. The goal ...
