Particle acceleration at supernova remnant shocks and the origin of cosmic rays (COSMIC RAY ORIGIN)
Date du début: 1 oct. 2007, Date de fin: 30 sept. 2009,
Cosmic rays are relativistic charged particles (mainly protons and a small fraction of heavier nuclei) hitting Earth from outer space. According to the most popular model for their origin, galactic cosmic rays are accelerated at the outer front of expanding supernova remnants, via the so- called diffusive shock acceleration mechanism. Even though the predictions of this model seem to broadly fit t ...
