Cosmic-ray acceleration and magnetic field amplification at supernova
remnant shocks

I will present the mechanism of particle acceleration at supernova remnant shock waves and the role the production of turbulent magnetic field by cosmic rays has on the process. The topic will be reviewed from the perspective of new observations in X- and gamma-ray bands. I will also show the recent results on the modeling of the magnetic field amplification in the vicinity of shocks with efficient particle acceleration and the implications these results have for the problem of the origin of high-energy cosmic rays.
