Implications of supernova remnant origin model of galactic cosmic rays on Gamma rays from young supernova remnants

It is widely believe that galactic cosmic rays are originated in supernova remnants (SNRs) where they are accelerated by diffusive shock acceleration process at supernova blast waves driven by expanding SNRs. In recent theoretical…
