LONG TERM OBSERVATIONS OF B2 1215+30 WITH VERITAS

E. Aliu, S. Archambault, T. Arlen, T. Aune et autres

We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHEs; E > 100 GeV) by VERITAS with a significance of 8.9σ and showed clear …

MULTIWAVELENGTH OBSERVATIONS OF LS I +61° 303 WITH VERITAS,SWIFT, ANDRXTE

V. A. Acciari, E. Aliu, T. Arlen, M. A. Bautista et autres

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 Swift , sampling nine 26.5 day orbital cycles between …

Radio Imaging of the Very-High-Energy γ-Ray Emission Region in the Central Engine of a Radio Galaxy

V. A. Acciari, E. Aliu, T. Arlen, M. A. Bautista et autres

Black Hole Energy Boost More than 20 galaxies are known to emit photons with energies a trillion times higher than those of visible light, but it is not known where this emission originates. These galaxies are part of a class of active …

EVIDENCE FOR LONG-TERM GAMMA-RAY AND X-RAY VARIABILITY FROM THE UNIDENTIFIED TeV SOURCE HESS J0632+057

V. A. Acciari, E. Aliu, T. Arlen, M. Beilicke et autres

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 massive Be star MWC 148 and has been suggested to resemble known TeV binary systems like LS …
