摘要:The transport of galactic cosmic rays from their production sites in the interstellar medium is essential for the understanding of several observations: secondaries nuclei produced by spallation reactions, abundances of radioactive elements, diffuse multi-wavelength backgrounds. Interaction with magnetic fluctuations in the interstellar medium are the main source of cosmic ray transport. The review addresses the recent analytical and numerical developments in the modelling of magnetic turbulence and charged particle interaction both inside cosmic-ray sources and in the interstellar medium. Issues on the cosmic ray escape from the sources and their radiative signatures in the local interstellar medium will be emphasize. Finally, the transport of low energy cosmic rays will be considered in the view of the problems related to the ionization of interstellar matter and the morphology of the diffuse electron-positron annihilation line.
