Very high energy gamma-ray observations of the galaxy clusters Abell 496 and Abell 85 with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
Aims: The nearby galaxy clusters Abell 496 and Abell 85 are studied in the very high energy (VHE, E > 100 GeV) band to investigate VHE cosmic rays (CRs) in this class of objects wh…
Very-High Energy Gamma-Ray Flux Limits for Nearby Active Galactic Nuclei
T. Herr, W. Hofmann
Combining the results of targeted observations, H.E.S.S. has accumulated a large amount of extra-galactic exposure at TeV energies. Due to its large field of view a considerable pa…
HESS J1023-575: Non-thermal particle acceleration associated with the young stellar cluster Westerlund 2
O. Reimer, J. Hinton, W. Hofmann +3
The results from H.E.S.S. observations towards Westerlund 2 are presented. The detection of very-high-energy gamma-ray emission towards the young stellar cluster Westerlund 2 in th…
H.E.S.S. observations of the Galactic Center region and their possible dark matter interpretation
H. E. S. S. collaboration, :, F. A. Aharonian
The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtractio…
Performance Limits for Cherenkov Instruments
W. Hofmann
The performance of Cherenkov instruments for the detection of very high energy gamma rays is ultimately limited by the fluctuations in the development of air showers. With particul…
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)…
