Download or read book Energy Budget in the High Energy Universe written by Junji Hisano and published by World Scientific. This book was released on 2007 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existence of materials with very high specific energies greatly exceeding the local virial temperature is best represented by cosmic rays, whose origin has long been a mystery. Recent astrophysical observations in X-ray, gamma-ray, neutrino, and high energy cosmic ray experiments, in conjunction with theoretical studies, have revealed various new aspects of the high energy universe, including promising candidates for cosmic ray acceleration sites. As each approach has its own advantages and limitations, it is expected that joint efforts by experimentalists and theorists in various related fields are essential. The contributions in this volume include observation of the universe through a wide range of techniques for detecting cosmic rays, neutrinos, X-rays and gamma-rays, as well as theoretical considerations in understanding their nature and astrophysical aspects.
