# Cosmic Ray Electron Acceleration at a Standing Shock

An image from a test calculation done to show the effects of radiative losses on a distribution of cosmic ray particles. In this case electrons suffer radiative losses due to synchrotron and inverse Compton as they are accelerated and move away from the shock. The particle distribution is shown in the image above and the movie below as a phase space diagram, where the x direction is the spatial coordinate with the shock being in the middle and the y coordinate being the log of the momentum variable and the plotted quantity being the log of the particle density times the momentum squared.

The particles undergo Diffusive Shock Acceleration with losses using the CGMV scheme^{[1]} (aka: Bigbins). The dimensions of the calculation are 10000 x 14. Below is a movie which shows the particle acceleration (the full movie is available at the bottom of the page):
