A possible association of the new VHE gamma-ray source HESS J1825--137 with the pulsar wind nebula G18.0--0.7
HESS Collaboration, F. A. Aharonian
We report on a possible association of the recently discovered very high-energy -ray source HESS J1825--137 with the pulsar wind nebula (commonly referred to as G 18.0--0.7) of…
Discovery of very high energy gamma-rays associated with an X-ray binary
H. E. S. S. Collaboration, :, F. Aharonian
X-ray binaries are composed of a normal star in orbit around a neutron star or stellar-mass black hole. Radio and X-ray observations have led to the presumption that some X-ray bin…
A low level of extragalactic background light as revealed by gamma-rays from blazars
H. E. S. S. Collaboration, :, F. Aharonian
The diffuse extragalactic background light consists of the sum of the starlight emitted by galaxies through the history of the Universe, and it could also have an important contrib…
Search for Pulsed VHE gamma-ray Emission from Young Pulsars with H.E.S.S
A. Konopelko, P. Chadwick, T. Eifert +6
Pulsars are commonly regarded as highly magnetized neutron stars, rotating up to several hundred times per second. Over 1,500 radio pulsars have been found so far, about 70 of whic…
Multi-wavelength observations of PKS 2155-304 with H.E.S.S
H. E. S. S. Collaboration, :, Aharonian
The High Energy Stereoscopic System (H.E.S.S.) has observed the high-frequency peaked BL Lac object PKS2155-304 in 2003 between October 19 and November 26 in Very High Energy (VHE)…
Observations of Mkn 421 in 2004 with H.E.S.S. at large zenith angles
H. E. S. S. Collaboration, :, F. Aharonian
Mkn 421 was observed during a high flux state for nine nights in April and May 2004 with the fully operational High Energy Stereoscopic System (H.E.S.S.) in Namibia. The observatio…
