4th International Meeting on High Energy Gamma-Ray Astronomy, Heidelberg : Allemagne (2008)
A Multiwavelength View of High-Energy Processes in the Galactic Center Region
A. Goldwurm1, 2
(12/2008)

The central 600 parsecs of our Galaxy can be considered a kind of laboratory for modern astrophysics because in the few square degrees of sky covered by this region, several important non-thermal high energy processes take place and can be studied in detail with the new telescopes operating both in on-ground and in space. In addition to the closest supermassive Black Hole to the solar system the region hosts several other compact and diffuse sources of high-energy radiation whose characteristics need to be studied at different wavelengths from radio to TeV gamma-rays in order to understand the physical processes at work. This paper presents a review of the characteristics of the Galactic Center region from a multiwavelength phenomenological point of view, and giving special emphasis to the sources and processes that shed ligth on the high-energy phenomena taking place in the region.
