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…
Serendipitous discovery of the unidentified extended TeV gamma-ray source HESS J1303-631
H. E. S. S. Collaboration, :, F. Aharonian
The serendipitous discovery of an unidentified extended TeVgamma-ray source close to the galactic plane named HESS J1303-631 at a significance of 21 standard deviations is reported…
A new population of very high energy gamma-ray sources in the Milky Way
F. A. Aharonian
Very high energy gamma-rays probe the long-standing mystery of the origin of cosmic rays. Produced in the interactions of accelerated particles in astrophysical objects, they can b…
Discovery of extended VHE gamma-ray emission from the asymmetric pulsar wind nebula in MSH 15-52 with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
The Supernova Remnant MSH 15-52 has been observed in very high energy (VHE) gamma-rays using the H.E.S.S. 4-telescope array located in Namibia. A gamma-ray signal is detected at th…
Search for TeV emission from the region around PSR B1706-44 with the H.E.S.S. experiment
H. E. S. S. Collaboration, :, F. Aharonian
The region around PSR B1706-44 has been observed with the H.E.S.S. imaging atmospheric Cherenkov telescopes in 2003. No evidence for gamma-ray emission in the TeV range was found a…
Very high energy gamma rays from the composite SNR G0.9+0.1
H. E. S. S. Collaboration, :, F. Aharonian
Very high energy (> 100 GeV) gamma-ray emission has been detected for the first time from the composite supernova remnant G0.9+0.1 using the H.E.S.S. instrument. The source is dete…
