Cosmic-Ray Propagation  

In General
* In the Milky Way galaxy: Self-induced turbulence from magnetic waves due to the cosmic rays themselves, dominates the energy dependence of the cosmic rays' diffusion constant below 230 GeV, while turbulence in preexisting magnetic fields dominates diffusion above this energy.
