Detection of Gamma Rays From a Starburst Galaxy
The HESS Collaboration, F. Acero
Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the remnants of which are thought to accelerate energetic cosmic rays up to energies of ~…
Correlation between the synchrotron and the inverse-Compton components, in the longterm light curve of GeV blazars
Bagmeet Behera, Marcus Hauser, Stefan J. Wagner
To explore the correlation in the GeV band (i.e. the inverse-Compton component) with the optical band (i.e. the synchrotron component) of blazars that are bright in high energies,…
A new strategy to select candidate blazars for VHE observation
Bagmeet Behera, Stefan J. Wagner
A new strategy to select candidate blazars for VHE observations, that gives an inherently complete sample from an all-sky compilation (excluding a narrow region around the galactic…
Simultaneous observations of PKS 2155-304 with H.E.S.S., Fermi, RXTE and ATOM: spectral energy distributions and variability in a low state
H. E. S. S., Fermi-LAT collaborations
We report on the first simultaneous observations that cover the optical, X-ray, and high energy gamma-ray bands of the BL Lac object PKS 2155-304. The gamma-ray bands were observed…
H.E.S.S. observations of gamma-ray bursts in 2003-2007
F. Aharonian
Very-high-energy (VHE; >~100 GeV) gamma-rays are expected from gamma-ray bursts (GRBs) in some scenarios. Exploring this photon energy regime is necessary for understanding the ene…
Spectral trends in the Very High Energy blazar sample due to EBL absorption
B. Behera, S. J. Wagner
The absorption of gamma-rays in the intergalactic medium due to the EBL (Extragalactic Background Light) causes the observed blazar spectrum to be fainter and softer than their int…
