Supernova remnants (SNRs) are believed to be the main source of Galactic cosmic rays with energies up to 10^15 eV. Strong SNR shocks provide ideal acceleration sites for electrons and maybe ions. In fact, among the identified Galactic gamma-ray sources the majority are associated with the violent, late phases of the stellar life. Good radio continuum observations at different frequencies...

I will review the class of galactic supernova remnants which show strong interactions with molecular clouds, revealed either through shock-excited masers or dense gas tracers. These remnants are preferentially found among the known GeV and TeV detections of supernova remnants. It has been argued that the masers and dense gas trace out the sites of hadronic particle acceleration. I will...

I present recent results on comparison between gamma ray SNRs and the interacting neutral clouds. I shall discuss on SNRs including RX J1713.7-3946, W28, W44 and RX J0852.0-4622 with an emphasis on the role of dense atomic and molecular gas in the interaction. In RX J1713.7-3946, I shall present highly clumped distribution of dense gas which exhibits good correlation with gamma rays and X...

With the detection of more than 7 Supernova Remnants (SNRs) by the Fermi-LAT telescope, we now have access to an energy range opening a window onto emission mechanisms not previously available for these objects. In particular in combination with multiwavelength observations, we are now better able to determine the probable particle populations accelerated by the SNRs as well as the...
