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 ...
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 ...
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 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 ...
Observation of gamma‐ray emission from the galaxy m87 above 250 gev with veritas1
(IOP Publishing, 2008-05-20)
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in active galactic nuclei from radio waves to TeV gamma-rays. Here we report the detection ...
The june 2008 flare of markarian 421 from optical to tev energies
(IOP Publishing, 2008-12-30)
We present optical, X-ray, high-energy ((sic) 30 GeV) and very high energy ((sic) 100 GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken between 2008 May 24 and June 23. A high-energy gamma-ray signal ...
Multiwavelength observations of markarian 421 in 2001 march: an unprecedented view on the x‐ray/tev correlated variability
(IOP Publishing, 2008-04-20)
We present a detailed analysis of week-long simultaneous observations of the blazar Mrk 421 at 2-60 keV X-rays (RXTE) and TeV gamma-rays (Whipple and HEGRA) in 2001. Accompanying optical monitoring was performed with the ...
