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…
A search for very high energy gamma-ray emission from the starburst galaxy NGC 253 with H.E.S.S
F. Aharonian et al.
We present the result of 28 hours of observations of the nearby starburst galaxy NGC 253 with the H.E.S.S. detector in 2003. We find no evidence for very high energy gamma-ray emis…
Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
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…
