The book reviews our current observational knowledge of the background radiation of the X-ray in the universe. The most relevant features of the X-ray background, discovered thirty years ago, are covered in detail. The contributions of the most recent space missions, including Ginga, Rosat, and the Astro-1 Shuttle flight are included. The topics covered embrace the spectrum of the radiation, isotropy on all angular scales and possible sources, such as active galactic nuclei and clusters of galaxies.

This book presents a review of the current observational knowledge and understanding of the cosmic X- ray background, discovered 30 years ago. The most relevant observational features of the cosmic X-ray background, its spectrum, high galactic latitude isotropy on all angular scales and its source content, are reviewed in detail. The contribution of the Ginga, Rosat and BBXRT space missions, play a major role in the discussions of the most recent estimates of the contribution to the X-ray intensity of different classes of sources, mostly Active Galactic Nuclei and Clusters of Galaxies. The fraction of resolved background intensity approaches 50 per cent at soft energies, where QSOs dominate. At higher photon energies, where most of the energy density of the background resides, the fraction directly resolved is smaller. Models for the residual intensity are discussed in the book, with particular emphasis on spectral as well as isotropy constraints.Review:
