A search for spectral hysteresis and energy-dependent time lags from X-ray and TeV gamma-ray observations of Mrk 421
A. U. Abeysekara, S. Archambault, A. Archer +220
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at di…
Very-high-energy observations of the binaries V 404 Cyg and 4U 0115+634 during giant X-ray outbursts
A. Archer, W. Benbow, R. Bird +62
Transient X-ray binaries produce major outbursts in which the X-ray flux can increase over the quiescent level by factors as large as . The low-mass X-ray binary V 404 Cyg an…
Discovery of Very High Energy Gamma Rays from 1ES 1440+122
VERITAS Collaboration, S. Archambault, A. Archer +87
The BL Lacertae object 1ES 1440+122 was observed in the energy range from 85 GeV to 30 TeV by the VERITAS array of imaging atmospheric Cherenkov telescopes. The observations, taken…
Very High Energy outburst of Markarian 501 in May 2009
E. Aliu, S. Archambault, A. Archer +108
The very high energy (VHE; E 100 GeV) blazar Markarian 501 was observed between April 17 and May 5 (MJD 54938--54956), 2009, as part of an extensive multi-wavelength campaign f…
VERITAS and Multiwavelength Observations of the BL Lacertae Object 1ES 1741+196
VERITAS Collaboration, A. U. Abeysekara, S. Archambault +85
We present results from multiwavelength observations of the BL Lacertae object 1ES 1741+196, including results in the very-high-energy -ray regime using the Very Energetic Radia…
Upper limits from five years of blazar observations with the VERITAS Cherenkov telescopes
S. Archambault, A. Archer, W. Benbow +78
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…
