Soft gamma-ray sources detected by INTEGRAL
D. Petry, V. Beckmann, H. Halloin +1
We aim to exploit the available INTEGRAL/SPI data to provide time-averaged spectra of the brightest soft gamma-ray sources. Employing a maximum-likelihood fit technique for our SPI…
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…
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…
