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 ...
