Cosmic ray propagation and interactions in the Galaxy

TL;DR

This paper reviews cosmic ray propagation in the Galaxy, focusing on self-consistent models where CR streaming instability generates turbulence that influences particle scattering and diffusion.

Contribution

It introduces self-consistent models of cosmic ray propagation that incorporate streaming instability and turbulence effects.

Findings

CR streaming instability drives turbulence affecting CR diffusion

Self-consistent models link CR anisotropy to turbulence generation

Turbulence determines scattering and diffusion of cosmic rays

Abstract

Cosmic ray propagation in the Galaxy is shortly reviewed. In particular we consider the self-consistent models of CR propagation. In these models CR streaming instability driven by CR anisotropy results in the Alfv\'enic turbulence which in turn determines the scattering and diffusion of particles.
