Tev gamma-ray observations of the galactic center
(IOP Publishing, 2004-05-18)
We report a possible detection of TeV gamma rays from the Galactic center by the Whipple 10 m gamma-ray telescope. Twenty-six hours of data were taken over an extended period from 1995 through 2003 resulting in a total ...
Search for high‐energy gamma rays from an x‐ray–selected blazar sample
(IOP Publishing, 2003-12-20)
Our understanding of blazars has been greatly increased in recent years by extensive multiwavelength observations, particularly in the radio, X-ray, and gamma-ray regions. Over the past decade the Whipple 10 m telescope ...
Detection of the bl lacertae object h1426+428 at tev gamma‐ray energies
(IOP Publishing, 2002-06-01)
A very high energy gamma-ray signal has been detected at the 5.5sigma level from H1426+ 428, an X-ray-selected BL Lacertae object at a redshift of 0.129. The object was monitored from 1995 to 1998 with the Whipple 10 m ...
Observation of m87 at 400 gev with the whipple 10 meter telescope
(IOP Publishing, 2004-07-20)
We present results from observations taken with the Whipple 10 m very high energy gamma-ray telescope with maximal sensitivity at 400 GeV during 39 hr between 2000 and 2003 in the direction of the giant radio galaxy M87. ...
Evidence for long-term gamma-ray and x-ray variability from the unidentified tev source hess j0632+057
(IOP Publishing, 2009-05-28)
HESS J0632+057 is one of only two unidentified very-high-energy gamma-ray sources which appear to be point-like within experimental resolution. It is possibly associated with the massive Be star MWC 148 and has been suggested ...
Discovery of very high energy gamma-ray radiation from the bl lac 1es 0806+524
(IOP Publishing, 2008-12-19)
The high-frequency-peaked BL Lacertae object 1ES 0806+524, at redshift z = 0.138, was observed in the very high energy (VHE) gamma-ray regime by VERITAS between 2006 November and 2008 April. These data encompass the two- ...
Veritas observations of a very high energy γ-ray flare from the blazar 3c 66a
(IOP Publishing, 2009-02-18)
The intermediate-frequency peaked BL Lacertae (IBL) object 3C 66A is detected during 2007-2008 in VHE ( very high energy; E > 100 GeV) gamma rays with the VERITAS stereoscopic array of imaging atmospheric Cherenkov ...
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 ...
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 ...
Discovery of very high energy gamma rays from pks 1424+240 and multiwavelength constraints on its redshift
(IOP Publishing, 2009-12-18)
We report the first detection of very high energy(83) (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140 GeV measured by VERITAS is well described ...
