H.E.S.S. detection of very-high-energy gamma-ray emission from the quasar PKS 0736+017

H. E. S. S. Collaboration, :, H. Abdalla +225

Flat-spectrum radio-quasars (FSRQs) are rarely detected at very-high-energies (VHE; E>100 GeV) due to their low-frequency-peaked SEDs. At present, only 6 FSRQs are known to emit VH…

H.E.S.S. observations of the flaring gravitationally lensed galaxy PKS 1830-211

H. E. S. S. Collaboration, :, H. Abdalla +224

PKS 1830-211 is a known macrolensed quasar located at a redshift of z=2.5. Its high-energy gamma-ray emission has been detected with the Fermi-LAT instrument and evidence for lensi…

Measurement of the EBL spectral energy distribution using the VHE gamma-ray spectra of H.E.S.S. blazars

H. E. S. S. Collaboration, :, H. Abdalla +256

Very high-energy gamma-rays (VHE, E>100 GeV) propagating over cosmological distances can interact with the low-energy photons of the extragalactic background light (EBL) and produc…

Search for photon line-like signatures from Dark Matter annihilations with H.E.S.S

H. E. S. S. Collaboration, :, A. Abramowski +201

Gamma-ray line signatures can be expected in the very-high-energy (VHE; E_γ> 100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal…

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 ~…

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…
