Fermi Bubbles as a Result of Star Capture in the Galactic Center
V. A. Dogiel, D. O. Chernyshov, K. -S. Cheng +3
Fermi has discovered two giant gamma-ray-emitting bubbles that extend nearly 10 kpc in diameter. We propose that periodic star capture processes by the galactic supermassive black…
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…
The Fundamental Plane of Gamma-ray Globular Clusters
C. Y. Hui, K. S. Cheng, Y. Wang +4
We have investigated the properties of a group of -ray emitting globular clusters (GCs) which have recently been uncovered in our Galaxy. By correlating the observed -ray lum…
