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 ...
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 upper limit on the very high energy emission from the radio galaxy ngc 1275
(IOP Publishing, 2009-11-16)
The recent detection by the Fermi gamma-ray space telescope of high-energy gamma-rays from the radio galaxy NGC 1275 makes the observation of the very high energy (VHE: E > 100 GeV) part of its broadband spectrum ...
Multiwavelength observations of markarian 421 in 2005-2006
(IOP Publishing, 2009-03-31)
Since 2005 September, the Whipple 10 m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five northern hemisphere blazars that have already been detected at the Whipple Observatory, Markarian 421 ...
