Cosmic rays are an essential part of the universe. This book reviews our present knowledge of cosmic rays, describing how they are born in a wide range of cosmic processes, how they are accelerated and how they behave during their journey across the Galaxy.
This is a textbook for graduate students entering the field but at the same time a cosmic ray manual for high energy astrophysicists and its first part easy to read for the general astronomer. The first part describes the standard model of cosmic rays based on our understanding of modern particle physics. The acceleration scenario is presented in some detail in supernovae explosions as well as in the passage of cosmic rays through the Galaxy. Experimental data in the atmosphere as well as underground are compared with theoretical models. The second part is devoted to contemporary cosmic ray research like the analysis of shower phenomena, the discussion of the end of the cosmic spectrum and, finally, high energy neutrino astronomy.
