Description

The very strong shocks generated by supernova explosions are the most promising candidates for the acceleration of Galactic cosmic rays. The synchrotron radiation of supernova remnants (SNRs) has long been observed in radio and X-rays, but only in recent years, since the gamma-ray emission in both the TeV and GeV energy range has become accessible via ground-based Cherenkov telescopes and the Fermi Large Area Telescope respectively, has it been possible to address questions oberservationally which hitherto belonged to the realm of theory. These pending questions refer to the nature of the accelerated particles, the efficiency of their acceleration and their maximum energy and associated magnetic field strength. The presentation will focus on the recent developments in the field of SNRs and the understanding of the phenomenologic aspects of these objects in the light of the new obervations carried out by the HESS and FERMI telescopes.
