| Review: |
The selected papers in this volume were presented at the International School of Cosmic Ray Astoohysics, held in Sicily. The book is divide into five sections. The first section deals with the high-energy frontier. One of the most intriguing physics problems is the question of the origin and acceleration of the highest energy cosmic rays. Two events, assigned energies beyond the maximum 'cut-off'-energy, have generated a burst of activity in this area. This section discusses this high energy 'frontier' and deals with both standard and cosmological explanations of these observations, and describes new experimental approaches to resolving the question. The second section covers cosmic gamma rays and neutrinos. The Compton Gamma Ray Observatory reported observing uniformity of the gamma ray bursts. The third section discussed cosmic ray matter and anti-matter. Among the cosmic rays are found both matter and anti-matter.The first part of the next decade should see major advances in the measurement of cosmic anti-matter. The last two sections cover energetic particles in the solar system and galactic astrophysics. |
