Veritas observations of the microquasar cygnus x-3
(IOP Publishing, 2013-12-03)
We report results from TeV gamma-ray observations of the microquasar Cygnus X-3. The observations were made with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) over a time period from 2007 June 11 ...
Spectral energy distribution of markarian 501: quiescent state versus extreme outburst
(IOP Publishing, 2011-02-03)
The very high energy (VHE; E > 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 ...
Very high energy outburst of markarian 501 in may 2009
(EDP Sciences, 2016-10-01)
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 was observed between April 17 and May 5 (MJD 54 938-54 956), 2009, as part of an extensive multiwavelength campaign from radio to VHE. Strong VHE yray ...
The most powerful flaring activity from the nlsy1 pmn j0948+0022
(Oxford University Press (OUP), 2014-11-27)
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma-rays, PMN J0948+0022 (z = 0.5846). A y -ray flare was observed by the Large ...
