We discuss the most recent developments in our understanding of the acceleration and propagation of cosmic rays up to the highest energies. In particular we specialize our discussion to three issues: (a) developments in the theory of particle acceleration at shock waves; (b) the transition from galactic to extragalactic cosmic rays; (c) implications of up-to-date observations for the origin of ultra high energy cosmic rays (UHECRs).

Abstract
We discuss the most recent developments in our understanding of the acceleration and propagation of cosmic rays up to the highest energies. In particular we specialize our discussion to three issues: (a) developments in the theory of particle acceleration at shock waves; (b) the transition from galactic to extragalactic cosmic rays; (c) implications of up-to-date observations for the origin of ultra high energy cosmic rays (UHECRs).File in questo prodotto:
