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…
The energy spectrum of cosmic-ray electrons at TeV energies
H. E. S. S. Collaboration, :, F. Aharonian
The very large collection area of ground-based gamma-ray telescopes gives them a substantial advantage over balloon/satellite based instruments in the detection of very-high-energy…
VHE Gamma-ray Afterglow Emission from Nearby GRBs
P. H. Tam, R. R. Xue, S. J. Wagner +3
Gamma-ray Bursts (GRBs) are among the potential extragalactic sources of very-high-energy (VHE) gamma-rays. We discuss the prospects of detecting VHE gamma-rays with current ground…
Discovery of gamma-ray emission from the shell-type supernova remnant RCW 86 with H.E.S.S
HESS Collaboration, F. Aharonian
The shell-type supernova remnant (SNR) RCW 86, possibly associated with the historical supernova SN 185, with its relatively large size (about 40' in diameter) and the presence of…
A search for a dark matter annihilation signal towards the Canis Major overdensity with H.E.S.S
HESS Collaboration, F. Aharonian
A search for a dark matter (DM) annihilation signal into -rays toward the direction of the Canis Major (CMa) overdensity is presented. The nature of CMa is still controversial a…
H.E.S.S. upper limits for Kepler's supernova remnant
HESS Collaboration, F. Aharonian
Observations of Kepler's supernova remnant (G4.5+6.8) with the H.E.S.S. telescope array in 2004 and 2005 with a total live time of 13 h are presented. Stereoscopic imaging of Chere…
Discovery of a VHE gamma-ray source coincident with the supernova remnant CTB 37A
HESS Collaboration, F Aharonian
The supernova remnant (SNR) complex CTB 37 is an interesting candidate for observations with Very High Energy (VHE) gamma-ray telescopes such as H.E.S.S. In this region, three SNRs…
Chandra and H.E.S.S. observations of the Supernova Remnant CTB 37B
HESS Collaboration, F. Aharonian
The >100 GeV gamma-ray source, HESS J1713-381, apparently associated with the shell-type supernova remnant (SNR) CTB 37B, was discovered using H.E.S.S. in 2006. X-ray follow-up obs…
Discovery of very-high-energy gamma-ray emission from the vicinity of PSR J1913+1011 with H.E.S.S
HESS Collaboration, F. Aharonian
The H.E.S.S. experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-…
Discovery of very high energy gamma-ray emission coincident with molecular clouds in the W28 (G6.4-0.1) field
HESS Collaboration, F Aharonian
We observed the W28 field (for ~40 h) at Very High Energy (VHE) gamma-ray energies (E>0.1 TeV) with the H.E.S.S. Cherenkov telescopes. A reanalysis of EGRET E>100 MeV data was also…
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…
An Exceptional VHE Gamma-Ray Flare of PKS 2155-304
