Highlight Talk: Recent Results from VERITAS
R. A. Ong, V. A. Acciari, T. Arlen +79
VERITAS is a state-of-the-art ground-based gamma-ray observatory that operates in the very high-energy (VHE) region of 100 GeV to 50 TeV. The observatory consists of an array of fo…
Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
V. A. Acciari, E. Aliu, T. Arlen +89
Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin…
VERITAS Upper Limit on the VHE Emission from the Radio Galaxy NGC 1275
VERITAS Collaboration, V. A. Acciari, E. Aliu +88
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…
Multiwavelength observations of a TeV-Flare from W Comae
VERITAS collaboration, V. A. Acciari, E. Aliu +167
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 ga…
A Topological Trigger System for Imaging Atmospheric-Cherenkov Telescopes
M. Schroedter, J. Anderson, K. Byrum +8
A fast trigger system is being designed as a potential upgrade to VERITAS, or as the basis for a future array of imaging atmospheric-Cherenkov telescopes such as AGIS. The scientif…
