Origin of Hydrogen Ionization in the 1 pc Galactic Central Region
D. O. Chernyshov, Gene C. K. Leung, K. S. Cheng +2
We study a possible connection between processes of gamma-ray emission and hydrogen ionization in a few pc of central region around Sgr A*. Previous investigations showed there is…
Spatial and Temporal Variations of the Diffuse Iron 6.4 keV Line in the Galactic Center Region
D. O. Chernyshov, V. A. Dogiel, M. Nobukawa +4
We analyze the diffuse Fe I K-alpha line generated in the diffuse interstellar molecular hydrogen by primary photons or subrelativistic protons injected by Sagittarius (Sgr) A*. We…
K-shell Emission of Neutral Iron Line from Sgr B2 Excited by Subrelativistic Protons
Vladimir Dogiel, Dmitrii Chernyshov, Katsuji Koyama +2
We investigated the emission of K iron line from the massive molecular clouds in the Galactic center (GC). We assume that at present the total flux of this emission consists of…
Origin of Thermal and Non-Thermal Hard X-ray Emission from the Galactic Center
Vladimir Dogiel, Dmitrii Chernyshov, Takayuki Yuasa +10
We analyse new results of Chandra and Suzaku which found a flux of hard X-ray emission from the compact region around Sgr A (r ~ 100 pc). We suppose that this emission is ge…
