Constraints on the very high energy emission from bl lacertae objects
(IOP Publishing, 2004-03-01)
We present results from observations of 29 BL Lacertae objects, taken with the Whipple Observatory 10 m gamma-ray telescope between 1995 and 2000. The observed objects are mostly at low redshift (z<0.2), but observations ...
The spectrum of tev gamma rays from the crab nebula
(IOP Publishing, 1998-08-20)
The spectrum of gamma rays from the Crab Nebula has been measured in the energy range 500 GeV-8 TeV at the Whipple Observatory by the atmospheric Cerenkov technique. Two methods of analysis that were used to derive spectra, ...
Veritas observations of the γ‐ray binary ls i +61 303
(IOP Publishing, 2008-06-01)
LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycles ( between 2006 September and 2007 ...
Discovery of high-energy and very high energy γ-ray emission from the blazar rbs 0413
(IOP Publishing, 2012-04-18)
We report on the discovery of high-energy (HE; E &gt; 0.1 GeV) and very high energy (VHE; E &gt; 100 GeV) gamma-ray emission from the high-frequency-peaked BL Lac object RBS 0413. VERITAS, a ground-based gamma-ray ...
Veritas observations of the bl lac object pg 1553+113
(IOP Publishing, 2015-01-09)
We present results from VERITAS observations of the BL Lac object PG 1553+113 spanning the years 2010, 2011, and 2012. The time-averaged spectrum, measured between 160 and 560 GeV, is well described by a power law with a ...
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 ...
