Very-high-energy gamma-radiation from supernova remnants as seen with H.E.S.S. — •Joachim Hahn¹, Anne Bochow¹, Henning Gast¹, Vincent Marandon¹, and Matthieu Renaud² — ¹Max-Planck-Institut für Kernphysik, Heidelberg, Deutschland — ²Laboratoire de Physique Théorique et Astroparticules, Montpellier, Frankreich

Supernova remnants (SNRs) are known to be emitters of very-high-energy (VHE, > 100 GeV) gamma-radiation and constitute one of the most intriguing source classes in VHE astronomy. While several hundred SNRs in our galaxy have been detected in radio, only few of them have been identified as VHE gamma-ray emitters. Using the extensive H.E.S.S. dataset on the central region of the Milky Way, the standard framework that links the origin of cosmic rays to the gamma-ray visibility of SNRs can now be tested. Here we present the ensemble of investigated SNRs and discuss constraints on the parameter space used in a theoretical model of hadronic VHE gamma-ray production.
