Non-thermal Radiation of Shell-type Supernova Remnants
We study the non-thermal emission from shell-type supernova remnants (SNRs) on the frame of a time-dependent model. In this model, the time-dependent non-thermal spectra of both primary electrons and protons as well as secondary elec tron/positron pairs can be calculated numerically by taking into account the evolution of the secondary electron/positron pairs produced from proton-proton (p-p) interac tions due to the acceler- ated protons collide with the ambient matter in an SNR. The multi-wavelength photon spectrum for a given SNR can be produced through leptonic processes such as electron/positron synchrotron radiation, bremsstrahlung and inverse Compton scattering as well as hadronic interaction. We have applied the model to explain the observed multi-waveband photon emissions from a young and a old shell-type SNRs.
