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…
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…
Discovery of the candidate pulsar wind nebula HESS J1718-385 in very-high-energy gamma-rays
S Collaboration, S. Carrigan, Y. A. Gallant +4
Motivated by recent detections of pulsar wind nebulae in very-high-energy (VHE) gamma rays, a systematic search for VHE gamma-ray sources associated with energetic pulsars was perf…
Morphological Studies of the PWN Candidate HESS J1809-193
Nu. Komin, S. Carrigan, A. Djannati-Ataï +4
The source HESS J1809-193 was discovered in 2006 in data of the Galactic Plane survey, followed by several re-observations. It shows a hard gamma-ray spectrum and the emission is c…
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…
