H.E.S.S. Observations of the Prompt and Afterglow Phases of GRB 060602B
HESS Collaboration, F. Aharonian
We report on the first completely simultaneous observation of a gamma-ray burst (GRB) using an array of Imaging Atmospheric Cherenkov Telescopes which is sensitive to photons in th…
Formation of hard VHE gamma-ray spectra of blazars due to internal photon-photon absorption
F. Aharonian, D. Khangulyan, L. Costamante
The energy spectra of TeV gamma-rays from blazars, after being corrected for intergalatic absorption in the Extragalactic Background Light (EBL), appear unusually hard, a fact that…
A Spectacular VHE Gamma-Ray Outburst from PKS 2155-304 in 2006
W. Benbow, C. Boisson, L. Costamante +10
Since 2002 the VHE (>100 GeV) gamma-ray flux of the high-frequency peaked BL Lac PKS 2155-304 has been monitored with the High Energy Stereoscopic System (HESS). An extreme gamma-r…
The hard synchrotron X-ray spectrum of the TeV BL Lac 1ES 1426+428
A. Wolter, V. Beckmann, G. Ghisellini +5
We have observed 1ES 1426+428 with INTEGRAL detecting it up to 150 keV. The spectrum is hard, confirming that this source is an extreme BL Lac object, with a synchrotron comp…
Search for Pulsed VHE Gamma-Ray Emission from Young Pulsars with H.E.S.S
The HESS Collaboration, F. Aharonian
We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescop…
A low density of the Extragalactic Background Light revealed by the H.E.S.S. spectra of the BLLac objects 1ES 1101-232 and H 2356-309
L. Costamante
The unexpectedly hard spectra measured by HESS for the BLLacs 1ES 1101-232 and H 2356-309 has allowed an upper limit on the Extragalactic Background Light (EBL) to be derived in th…
