The Galactic Center and Activity

  • Yoshiaki Sofue
Part of the Lecture Notes in Physics book series (LNP, volume 935)


The galactic center has been a special object in astronomy since its discovery by C. Jansky as one of the brightest radio sources. It is a particularly useful object for understanding the nuclear activities of galaxies and their central black holes because of the small distance from us. Although nuclei of galaxies are not identical to the galactic center (GC), their fundamental physics and exhibited phenomena are in general similar, because the galactic structure and the composing material are similar, or sometimes almost the same. Hence, the galactic center and nuclear regions of galaxies are in general essentially the same. In this chapter various radio observational phenomena in the galactic center are reviewed and compared with those in active nuclei in galaxies. They are discussed in terms of energetic activities in the nuclear regions such as explosions and starbursts.
