SSC scenario for TeV emission from non-blazar AGNs
J. -P. Lenain, C. Boisson, H. Sol
M87 is the first extragalactic source detected in the TeV gamma-ray domain that is not a blazar, its large scale jet not being aligned to the line of sight. We present here a multi…
A synchrotron self-Compton scenario for the very high energy gamma-ray emission of the radiogalaxy M87
Jean-Philippe Lenain, Catherine Boisson, Hélène Sol +1
M87 is the first extragalactic source detected in the TeV range that is not a blazar. With the increasing performances of ground-based Cherenkov telescopes, we can now probe the va…
A Spectacular VHE Gamma-Ray Outburst from PKS 2155-304 in 2006
W. Benbow, C. Boisson, L. Costamante +10
Since 2002 the VHE (>100 GeV) gamma-ray flux of the high-frequency peaked BL Lac PKS 2155-304 has been monitored with the High Energy Stereoscopic System (HESS). An extreme gamma-r…
Multi-wavelength Observations of PG 1553+113 with HESS
HESS Collaboration, W. Benbow, C. Boisson +2
Very high energy (VHE; >100 GeV) gamma-ray observations of PG 1553+113 were made with the High Energy Stereoscopic System (HESS) in 2005 and 2006. A strong signal, ~10 standard dev…
Unveiling the broad band X-ray continuum and iron line complex in Mkr 841
P. O. Petrucci, G. Ponti, G. Matt +7
Mkr 841 is a bright Seyfert 1 galaxy known to harbor a strong soft excess and a variable K iron line. It has been observed during 3 different periods by XMM for a total cumulate…
Search for Pulsed VHE Gamma-Ray Emission from Young Pulsars with H.E.S.S
The HESS Collaboration, F. Aharonian
We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescop…
