Test of models of the cosmic infrared background with multiwavelength observations of the blazar 1es 1218+30.4 in 2009
(IOP Publishing, 2014-06-04)
We present the results of a multi-wavelength campaign targeting the blazar 1ES 1218+30.4 with observations with the 1.3 m McGraw-Hill optical telescope, the Rossi X-ray Timing Explorer (RXTE), the Fermi Gamma-Ray Space ...
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) ...
Very-high-energy γ-ray observations of the blazar 1es 2344+514 with veritas
(Oxford University Press (OUP), 2017-07-17)
We present very-high-energy gamma-ray observations of the BL Lac object 1ES 2344+514 taken by the Very Energetic Radiation Imaging Telescope Array System between 2007 and 2015. 1ES 2344+514 is detected with a statistical ...
Veritas observations of the bl lac object 1es 1218+304
(IOP Publishing, 2009-04-07)
The VERITAS collaboration reports the detection of very-high-energy gamma-ray emission from the high-frequency-peaked BL Lac object 1ES 1218+304 located at a redshift of z = 0.182. A gamma-ray signal was detected with a ...
Observation of gamma‐ray emission from the galaxy m87 above 250 gev with veritas1
(IOP Publishing, 2008-05-20)
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in active galactic nuclei from radio waves to TeV gamma-rays. Here we report the detection ...
Veritas observations of the tev binary ls i +61° 303 during 2008-2010
(IOP Publishing, 2011-08-09)
We present the results of observations of the TeV binary LS I + 61 degrees 303 with the VERITAS telescope array between 2008 and 2010, at energies above 300 GeV. In the past, both ground-based gamma-ray telescopes VERITAS ...
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 ...
Multiband variability studies and novel broadband sed modeling of mrk 501 in 2009
(EDP Sciences, 2017-07-01)
Aims. We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1, which includes, among other instruments, ...
