Cosmic Rays in Galactic and Extragalactic Magnetic Fields
by F. Aharonian, A. Bykov, E. Parizot, V. Ptuskin, A. Watson
Publisher: arXiv 2011
Number of pages: 43
Description:
We briefly review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the X-ray and gamma-ray observations that shed light on the origin of the galactic cosmic rays and the challenging results of Pierre Auger Observatory on the ultra high energy cosmic rays.
