Discovery of very high energy gamma rays from pks 1424+240 and multiwavelength constraints on its redshift
(IOP Publishing, 2009-12-18)
We report the first detection of very high energy(83) (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140 GeV measured by VERITAS is well described ...
Veritas deep observations of the dwarf spheroidal galaxy segue 1
(American Physical Society (APS), 2012-03-05)
The VERITAS array of Cherenkov telescopes has carried out a deep observational program on the nearby dwarf spheroidal galaxy Segue 1. We report on the results of nearly 48 hours of good quality selected data, taken between ...
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 ...
Detection of pulsed gamma rays above 100 gev from the crab pulsar
(American Association for the Advancement of Science (AAAS), 2011-10-06)
We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 giga-electron volts (GeV) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) array of atmospheric Cherenkov ...
