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…
Detection of Extended VHE Gamma Ray Emission from G106.3+2.7 with VERITAS
VERITAS Collaboration, V. A. Acciari, E. Aliu +80
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…
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…
Evidence for long-term Gamma-ray and X-ray variability from the unidentified TeV source HESS J0632+057
VERITAS Collaboration, V. A. Acciari, E. Aliu +79
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 m…
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…
What Are Gamma-Ray Bursts -- The Unique Role of Very High Energy Gamma-Ray Observations
D. A. Williams, A. D. Falcone, M. G. Baring +20
Gamma-ray bursts (GRBs) have been an enigma since their discovery forty years ago. However, considerable progress unraveling their mysteries has been made in recent years. Developm…
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…
VERITAS Observations of a Very High Energy Gamma-ray Flare from the Blazar 3C 66A
VERITAS Collaboration, V. A. Acciari, E. Aliu +87
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 arr…
