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…

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…

VERITAS observations of M87 from 2007 to present

C. M. Hui

M87 is a nearby radio galaxy and because of its misaligned jet, it is possible to correlate detailed spatially-resolved emission regions in the radio, optical to X-ray waveband wit…

The June 2008 flare of Markarian 421 from optical to TeV energies

R. M. Wagner, I. Donnarumma, J. Grube +6

We present optical to very-high energy (VHE) gamma-ray observations of Mrk 421 between 2008 May 24 and June 23. A high-energy (HE) gamma-ray signal was detected by AGILE-GRID durin…

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…
