Scientific paper

Origins of the very hot component in the galactic ridge are discussed. The formation of such a hot component by supernova shock wave heating requires an unconfortably high rate of supernova explosion. An explosion with energy of 10 to the 58th power erg may have occurred a few million years ago in the galactic center and produced a shock wave to heat the matter in the galactic ridge. The observed X-ray features can be consistently explained with this model. The ejecta of the explosion may contain Al-26 of 10 solar masses which can give 1.8 MeV gamma rays, as observed.
