'With more than 25 years since the first edition, this second edition ... has been revised and extended by about 150 pages to account for the progress and important discoveries made in the field since then. These comprise the famous neutrino oscillations, the cutoff in ultrahigh-energy cosmic ray spectra, Tera-electronvolt gamma rays from galactic sources and the unexpected excess of high-energy positrons and astrophysical neutrinos. ... The text is well written and presents all material with mathematical rigour and a large number of references to scientific publications ... The text is accompanied by numerous black-and-white figures, mainly of spectra. It has an appendix with additional material and a helpful index. ... It can be recommended mainly for graduate students and researchers from both theory and experiment who want a thorough introduction to the phenomenology and to the theoretical background of cosmic ray physics at the junction of particle physics and astronomy.'
