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) ... -
Discovery of high-energy and very high energy γ-ray emission from the blazar rbs 0413
(IOP Publishing, 2012-04-18)We report on the discovery of high-energy (HE; E > 0.1 GeV) and very high energy (VHE; E > 100 GeV) gamma-ray emission from the high-frequency-peaked BL Lac object RBS 0413. VERITAS, a ground-based gamma-ray ... -
Long term observations of b2 1215+30 with veritas
(IOP Publishing, 2013-11-27)We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHEs; E > 100 GeV) by VERITAS with a significance of 8.9s ... -
Multiwavelength observations and modeling of 1es 1959+650 in a low flux state
(IOP Publishing, 2013-08-27)We report on the VERITAS observations of the high-frequency peaked BL Lac object 1ES 1959+650 in the period 2007-2011. This source is detected at TeV energies by VERITAS at 16.4 standard deviation (sigma) significance in ... -
Rapid tev gamma-ray flaring of bl lacertae
(IOP Publishing, 2012-12-19)We report on the detection of a very rapid TeV gamma-ray flare from BL Lacertae on 2011 June 28 with the Very Energetic Radiation Imaging Telescope Array System (VERITAS). The flaring activity was observed during a 34.6 ...
