Opis

The articles in this book deal with energetic hadron processes near astrophysical compact objects, including compact binary systems and active galactic nuclei. A variety of observational results suggest that relativistic hadrons can be produced in the vicinity of these objects. Amongthe topics treated in detail are the question whether a large fraction of the energy produced by active galactic nuclei is channeled into a population of relativistic protons and the problem of the origin of very high and ultra-high energy gamma rays from galactic compact sources.

O autorze

The book deals with energetic hadron processes near astrophysical compact objects. The consequences of relativistic hadron production in the vicinity of these objects are explored. Hadron-initiated electron-positron pair cascades, very high and ultra-high gamma rays, neutrinos, and relativistic free neutrons are discussed.
