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

http://arxiv.org/abs/1906.12240


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.
