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…
Observations of the Sagittarius Dwarf galaxy by the H.E.S.S. experiment and search for a Dark Matter signal
HESS Collaboration, F. Aharonian
Observations of the Sagittarius dwarf spheroidal (Sgr dSph) galaxy were carried out with the H.E.S.S. array of four imaging air Cherenkov telescopes in June 2006. A total of 11 hou…
HESS Observations and VLT Spectroscopy of PG 1553+113
HESS Collaboration, F. Aharonian
AIMS: The properties of the very high energy (VHE; E>100 GeV) gamma-ray emission from the high-frequency peaked BL Lac PG 1553+113 are investigated. An attempt is made to measure t…
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…
H.E.S.S. observations of the supernova remnant RX J0852.0-4622
H. E. S. S. Collaboration, :, M. Lemoine-Goumard +4
The shell-type supernova remnant RX J0852.0-4622 was detected in 2004 and re-observed between December 2004 and May 2005 with the High Energy Stereoscopic System (H.E.S.S.), an arr…
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…
An Exceptional VHE Gamma-Ray Flare of PKS 2155-304
F. Aharonian
The high-frequency peaked BL Lac PKS 2155-304 at redshift z=0.116 is a well-known VHE (>100 GeV) gamma-ray emitter. Since 2002 its VHE flux has been monitored using the H.E.S.S. st…
Detection of VHE gamma-ray emission from the distant blazar 1ES 1101-232 with H.E.S.S. and broadband characterisation
H. E. S. S. Collaboration, :, F. Aharonian
The blazar 1ES 1101-232 was observed with the High Energy Stereoscopic System (H.E.S.S.) of Atmospheric Cherenkov Telescopes (ACT) in 2004 and 2005, for a live time of 43 hours. VH…
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…
Discovery of two candidate pulsar wind nebulae in very-high-energy gamma rays
H. E. S. S. Collaboration, :, F. Aharonian
We present the discovery of two very-high-energy gamma-ray sources in an ongoing systematic search for emission above 100 GeV from pulsar wind nebulae in survey data from the H.E.S…
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…
