A search for dark matter annihilation with the whipple 10 m telescope
(IOP Publishing, 2008-05-10)
We present observations of the dwarf galaxies Draco and Ursa Minor, the Local Group galaxies M32 and M33, and the globular cluster M15 conducted with the Whipple 10 m gamma-ray telescope to search for the gamma-ray signature ...
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 ...
Veritas discovery of >200 gev gamma-ray emission from the intermediate-frequency-peaked bl lacertae object w comae
(IOP Publishing, 2008-08-20)
We report the detection of very high energy gamma- ray emission from the intermediate- frequency- peaked BL Lacertae object W Comae (z = 0.102) by VERITAS. The source was observed between 2008 January and April. A strong ...
Multiwavelength observations of a tev-flare from w comae
(IOP Publishing, 2009-11-24)
We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z = 0.102) during a strong outburst of very high energy gamma-ray emission in 2008 June. The very ...
Multiwavelength observations of ls i +61° 303 with veritas,swift, andrxte
(IOP Publishing, 2009-07-08)
We present results from a long-term monitoring campaign on the TeV binary LSI +61 degrees 303 with VERITAS at energies above 500 GeV, and in the 2-10 keV hard X-ray bands with RXTE and Swift, sampling nine 26.5 day orbital ...
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- ...
Observation of extended very high energy emission from the supernova remnant ic 443 with veritas
(IOP Publishing, 2009-06-01)
We present evidence that the very high energy (VHE, E > 100 GeV) gamma-ray emission coincident with the supernova remnant IC 443 is extended. IC 443 contains one of the best studied sites of supernova remnant/molecular ...
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 ...
Detection of extended vhe gamma ray emission from g106.3+2.7 with veritas
(IOP Publishing, 2009-08-25)
We report the detection of very-high-energy (VHE) gamma-ray emission from supernova remnant (SNR) G106.3+2.7. Observations performed in 2008 with the VERITAS atmospheric Cherenkov gamma-ray telescope resolve extended ...
Radio imaging of the very-high-energy -ray emission region in the central engine of a radio galaxy
(American Association for the Advancement of Science (AAAS), 2009-07-02)
The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to energies exceeding 10(12) electron ...
