1st Abstract

I will discuss how time dependent solutions of particle acceleration by strong shocks can explain anomalous rigidity distributions of cosmic rays and broken-power gamma-ray spectra of SNRs. Considering the feedback of accelerated particles on the shock dynamics, the model may also explain the radio spectral hardening of SNRs with age.
