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 ...
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 ...
Search for a correlation between very-high-energy gamma rays and giant radio pulses in the crab pulsar
(IOP Publishing, 2012-11-16)
We present the results of a joint observational campaign between the Green Bank radio telescope and the VERITAS gamma-ray telescope, which searched for a correlation between the emission of very-high-energy (VHE) gamma ...
A search for very high energy gamma rays from the missing link binary pulsar j1023+0038 with veritas
(American Astronomical Society, 2016-11-08)
The binary millisecond radio pulsar PSR J1023+0038 exhibits many characteristics similar to the gamma-ray binary system PSR B1259-63/LS 2883, making it an ideal candidate for the study of high-energy nonthermal emission. ...
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 ...
Multiwavelength observations of mrk 501 in 2008
(EDP Sciences, 2014-12-17)
Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (>100 GeV, hereafter VHE). Mrk 501 is one of the brightest blazars at TeV energies and ...
Long-term tev and x-ray observations of the gamma-ray binary hess j0632+057
(IOP Publishing, 2013-12-20)
HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations with ground-based observatories in both the northern and southern hemispheres. Here we report on long-term observations ...
A search for pulsations from geminga above 100 gev with veritas
(IOP Publishing, 2015-02-09)
We present the results of 71.6 hr of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS between 2007 November and 2013 February were ...
Veritas observations of the unusual extragalactic transient swift j164449.3+573451
(IOP Publishing, 2011-08-24)
We report on very high energy (>100 GeV) gamma-ray observations of Swift J164449.3+573451, an unusual transient object first detected by the Swift Observatory and later detected by multiple radio, optical, and X-ray ...
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 ...
