Cosmic ray acceleration by shocks: spectral steepening due to turbulent magnetic field amplification

arXiv:1906.12240 · doi:10.1093/mnras/stz1805

Abstract

We show that the energy required to turbulently amplify magnetic field during cosmic ray (CR) acceleration by shocks extracts energy from the CR and steepens the CR energy spectrum.
