Evolution of Magnetic Fields in Supernova Remnants

Abstract

Supernova remnants (SNR) are now widely believed to be a source of cosmic rays (CRs) up to an energy of 10 eV. The magnetic fields required to accelerate CRs to sufficiently high energies need to be much higher than can result from compression of the circumstellar medium (CSM) by a factor 4, as is the case in strong shocks. Non-thermal synchrotron maps of… (More)
