0067-0057 a-Ray Observatory and ESA‘s INTEGRAL mission, as well as of ground-based instruments have open new views into the high-energy Universe. Different classes of cosmic gamma-ray sources have been now detected at different energies, in addition to young radio pulsars and gamma-ray bursts, the classical o

强所

A multiwavelength approach, using X-ray, optical, and radio data, is often needed to understand the nature of these sources. This chapter reviews the technique of identification of EGRET sources using multiwavelength studies of the gamma-ray fields.

Lederach’s Peacebuilding Frameworkty of EGRET unidentified sources is described. We summarize the current knowledge of the high energy γ-ray sky and discuss the astrophysics of known and some prospective classes of γ-ray emitters. Besides, we describe the potential of GLAST to resolve old puzzles and to discover new classes of sources.
