This volume, marking the 20th Anniversary of the International School of Cosmic Ray Astrophysics, provides a wide-ranging overview of modern astrophysics -- from the infra-red to X-rays and g-rays, from neutrinos to galactic cosmic rays, and from shock wave acceleration to cosmology. The separate topics contain both background information and the newest results in the field, making the discussion suitable for the nonexpert and the expert alike. Featured are high energy neutrinos (including the new generation of experiments coming on line), new results from X-ray astronomy and from the...

The symbiosis between particles physics and cosmology has virtually become a conjugal relationship. Hence the 9th Biennial Course of the International School of Cosmic-Ray Astrophysics was designed to bridge these formerly disparate disciplines. This NATO Advanced Study Institute took place at the Ettore Majorana Centre in Erice, Italy, June 20-30, 1992. Seventy participants from 17 countries participated in lively interactions and enjoyed the stimulating lectures that form the basis for this volume. The book includes current advances in both astrophysics (cosmic gamma ravs, X-rays, cosmic...

This text comprises selected lectures presented in the 9th course of the International School of Cosmic-Ray Astrophysics held at the Ettore Majorana Centre in Erice, Sicily, May 7-18, 1994. Devoted to problems and prospects in high-energy astrophysics and cosmology, the major areas explored are: gamma- ray, X-ray, and neutrino astronomies; cosmic rays; pulsars and supernova remnants; and cosmology, as well as cosmogony. Among the principal developments in gamma-ray astrophysics are those generated by the Compton Gamma Ray Observatory. Cosmic neutrinos at MeV energies, i.e. those from the Sun...

The Galactic cosmic rays have far-reaching effects on the interstellar medium, and they are, in turn, profoundly affected by the particles and fields in space. Supernova remnants and their expanding shock fronts pervade the Galaxy, heating the interstellar medium, and accelerating the cosmic rays. The interplay among the cosmic rays, the interstellar medium in which they propagate, and supernovae has been investigated for decades; yet these studies have generated as many enigmas as they have resolved. These puzzles continue to challenge observers and theorists alike. th This volume is devoted...
