Currents in Astrophysics and Cosmology focuses primarily on cosmic-ray physics, X-ray, gamma-ray and neutrino astronomy and cosmology, the main research areas of Professor Maurice M. Shapiro, whose 75th birthday the collection of articles celebrates. Professor Shapiro is internationally distinguished for his contributions to the development of cosmic-ray physics. Each chapter is written by a leading scientist in the field. The scope extends from the inner solar system to distant radio galaxies. The book is ideal for graduate students and scientists working in cosmic-ray astrophysics. This valuable survey will be welcomed not only for its articles by world-renowned scientists but also for its coverage of many topics in high-energy astrophysics, the combination of which makes the book unique.
