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 ...
Very-high energy observations of the galactic center region by veritas in 2010-2012
(IOP Publishing, 2014-07-16)
The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the ...
Tev gamma-ray observations of the galactic center ridge by veritas
(American Astronomical Society, 2016-04-22)
The Galactic Center ridge has been observed extensively in the past by both GeV and TeV gamma-ray instruments revealing a wealth of structure, including a diffuse component and the point sources G0.9+0.1 (a composite ...
Deep broadband observations of the distant gamma-ray blazar pks 1424+240
(IOP Publishing, 2014-03-28)
We present deep VERITAS observations of the blazar PKS 1424+240, along with contemporaneous Fermi Large Area Telescope, Swift X-ray Telescope, and Swift UV Optical Telescope data between 2009 February 19 and 2013 June 8. ...
Constraints on cosmic rays, magnetic fields, and dark matter from gamma-ray observations of the coma cluster of galaxies with veritas andfermi
(IOP Publishing, 2012-09-11)
Observations of radio halos and relics in galaxy clusters indicate efficient electron acceleration. Protons should likewise be accelerated and, on account of weak energy losses, can accumulate, suggesting that clusters may ...
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 ...
Upper limits from five years of blazar observations with the veritas cherenkov telescopes
(American Astronomical Society, 2016-05-18)
Between the beginning of its full-scale scientific operations in 2007 and 2012, the VERITAS Cherenkov telescope array observed more than 130 blazars; of these, 26 were detected as very-high-energy (VHE; E > 100 GeV) ...
Veritas observations of day-scale flaring of m 87 in 2010 april
(IOP Publishing, 2012-02-01)
VERITAS has been monitoring the very-high-energy (VHE; > 100 GeV) gamma-ray activity of the radio galaxy M87 since 2007. During 2008, flaring activity on a timescale of a few days was observed with a peak flux of ...
Constraints on very high energy emission from grb 130427a
(IOP Publishing, 2014-10-10)
Prompt emission from the very fluent and nearby (z = 0.34) gamma-ray burst GRB130427A was detected by several orbiting telescopes and by ground-based, wide-field-of-view optical transient monitors. Apart from the intensity ...
Spatially resolving the very high energy emission from mgro j2019+37 with veritas
(IOP Publishing, 2014-05-23)
We present very high energy (VHE) imaging of MGRO J2019+37 obtained with the VERITAS observatory. The bright extended (similar to 2 degrees) unidentified Milagro source is located toward the rich star formation region ...
