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 ...
Investigating broadband variability of the tev blazar 1es 1959+650
(IOP Publishing, 2014-12-03)
We summarize broadband observations of the TeV-emitting blazar 1ES 1959+650, including optical R-band observations by the robotic telescopes Super-LOTIS and iTelescope, UV observations by Swift Ultraviolet and Optical ...
Multiwavelength observations of the previously unidentified blazar rx j0648.7+1516
(IOP Publishing, 2011-11-15)
We report on the VERITAS discovery of very high energy (VHE) gamma-ray emission above 200 GeV from the high-frequency-peaked BL Lac (HBL) object RX J0648.7+1516 (GB J0648+1516), associated with 1FGL J0648.8+1516. The photon ...
Spectral energy distribution of markarian 501: quiescent state versus extreme outburst
(IOP Publishing, 2011-02-03)
The very high energy (VHE; E &gt; 100 GeV) blazar Markarian 501 (Mrk 501) has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical processes within the jets ...
