Cosmic rays in our galaxy

Séminaire IPAG de Alexandre Marcowith (LUPM, Montpellier), jeudi 12 septembre 2012 à 11h00, IPAG seminar room

2012 marks the centenary of cosmic rays discovery by Austrian physicist Victor Hess. Although the origin of this cosmic rays remains a major puzzles for modern astrophysics, in the recent years our understanding of this phenomenon has greatly improved thanks to observations (notably at the highest energies), progress in the microphysics of shock and phenomenology of transport in the interstellar medium. In this seminar we will present these various aspects, and we will discuss open questions on the galactic cosmic radiation and its link with other ingredients of the star formation cycle.
