Cosmic Ray Diffusion in the Galaxy

Part of the Springer Theses book series (Springer Theses)

Abstract

In this Chapter I will describe the physics that stands behind the problem of CR propagation. Since the battlefield in which CR propagation takes place is the interstellar medium (ISM) of our Galaxy, I will first present a complete description of the Galactic environment and its components, with particular attention to the interstellar gas, the magnetic field (related to CR diffusion and spallation) and the distribution of pulsars and Supernova Remnants (related to CR origin); I will point out the deep interplay that exist between these components that continuously interact one another: the gas triggers star formation, massive stars quickly generate Supernova explosions that accelerate CRs, the gas returns back again in the ISM and the released energy triggers the turbulence that is responsible of the CR random walk.
