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…

Simultaneous Multiwavelength Observations of Markarian 421 During Outburst

The VERITAS Collaboration, I. de la Calle Perez, A. Ibarra +2

We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X…

Multiwavelength Observations of Mrk 501 in 2008

D. Kranich, D. Paneque, A. Cesarini +16

The well-studied VHE (E >100 GeV) blazar Mrk 501 was observed between March and May 2008 as part of an extensive multiwavelength observation campaign including radio, optical, X-ra…

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…

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…
