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…
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…
Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy
The VERITAS Collaboration, the VLBA 43 GHz M 87 Monitoring Team, the H. E. S. S. Collaboration +1
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 particle…
Observation of Extended VHE Emission from the Supernova Remnant IC 443 with VERITAS
VERITAS Collaboration, V. A. Acciari, E. Aliu +90
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-studie…
Multiwavelength Observations of LS I +61 303 with VERITAS, Swift and RXTE
VERITAS Collaboration, V. A. Acciari, E. Aliu +83
We present results from a long-term monitoring campaign on the TeV binary LSI +61 303 with VERITAS at energies above 500 GeV, and in the 2-10 keV hard X-ray bands with RXTE and Swi…
Multiwavelength Observations of Markarian 421 in 2005 - 2006
D. Horan, V. A. Acciari, S. M. Bradbury +71
Since September 2005, the Whipple 10m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five Northern Hemisphere blazars that have already been detected at t…
