A wide range of topics are covered, ranging from supernovae to active galactic nuclei, cosmic gamma rays to neutrinos and dark matter. The basic emphasis is on physics / astrophysics and experimental / observational techniques, scientific implications of current results, and prospects for future advances. The fields surveyed are in rapid development and the exploration of our high energy universe is proceeding rapidly, with exciting new discoveries. What unifies much of the new data is the idea of particle acceleration to enormous energies and the subsequent interactions of the particles with the local medium. It this focus that makes the book both timely and an important contribution to the field.

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 to selected lectures presented in the 7 Course of the International School of Cosmic-Ray Astrophysics in Erice, Italy in July-August, 1990. Alltogether, some 400 participants have attended the biennial sessions of this School since its inception in 1978. As its name implies, the School deals with cosmic-ray phenomena viewed in the broader context of astrophysics. Students and Lecturers are attracted from many astrophysical disciplines. Like earlier courses in this series, the present one was organized under the aegis of the Ettore Majorana Centre as a NATO Advanced Study Institute. Given the diverse scientific backgrounds of the students, it was deemed useful to include lectures at the introductory level. Other lectures and contributed talks were at a more advanced level, featuring new developments. If this collection is useful pedagogically, and if it provides some stimulus and information for the mature research worker, then the editors will feel well rewarded.

“Neutrinos and Explosive Events in the Universe” brought together experts from diverse disciplines to offer a detailed view of the exciting new work in this part of High Energy Astrophysics. Sponsored by NATO as an Advanced Study Institute, and coordinated under the auspices of the International School of Cosmic Ray Astrophysics (14th biennial course), the ASI featured a full program of lectures and discussion in the ambiance of the Ettore Majorana Centre in Erice, Italy, including visits to the local Dirac and Chalonge museum collections as well as a view of the cultural heritage of southern Sicily. Enri- ment presentations on results from the Spitzer Infrared Space Telescope and the Origin of Complexity complemented the program. This course was the best attended in the almost 30 year history of the School with 121 participants from 22 countries. The program provided a rich ex- rience, both introductory and advanced, to fascinating areas of observational Astrophysics Neutrino Astronomy, High Energy Gamma Ray Astronomy, P- ticle Astrophysics and the objects most likely responsible for the signals - plosions and related phenomena, ranging from Supernovae to Black Holes to the Big Bang. Contained in this NATO Science Series volume is a summative formulation of the physics and astrophysics of this newly emerging research area that already has been, and will continue to be, an important contributor to understanding our high energy universe.

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 γ-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 infra-red, particle acceleration in astrophysical plasmas, new results on the composition of cosmic rays (spanning six decades in energy), and cosmology.

This volume covers a number of areas of high energy astrophysics, focusing on the current status/understanding of the field, outstanding problems to be resolved and, in many cases, new experiments that will be providing some answers after the turn of the century. Featured are the following topics: high energy frontier, including the enigmatic observations of events beyond the cut-off energy; gamma ray bursts — local and cosmological models; high energy astrophysical neutrinos; cosmic ray matter and antimatter; solar system astrophysics; and galactic physics. The discussion is suitable for the nonexpert and expert alike.
