Description
Cosmic ray propagation is determined by the properties of interstellar turbulence. The multiphase nature of ISM and diversity of driving mechanisms give rise to spatial variation of turbulence properties. In the meantime, precision astroparticle experiments pose challenges to the conventional picture of homogeneous and isotropic transport of cosmic rays (CRs). We are beginning a new chapter of CR propagation research when studies of particle transport and interstellar turbulence can confront each other. I shall review our current understandings of the fundamental processes governing cosmic ray propagation, different regimes of particle transport, augmented with insight from multi-wavelength observations. Challenges and issues from bridging the current CR propagation paradigm and astroparticle measurements will be discussed.
