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…
Particle acceleration and the origin of gamma-ray emission from Fermi Bubbles
D. O. Chernyshov, K. -S. Cheng, V. A. Dogiel +3
Fermi LAT has discovered two extended gamma-ray bubbles above and below the galactic plane. We propose that their origin is due to the energy release in the Galactic center (GC) as…
Probing the tidal disruption flares of massive black holes with high-energy neutrinos
Xiang-Yu Wang, Ruo-Yu Liu, Zi-Gao Dai +1
The recently discovered high-energy transient Swift J164449.3+573451 (Sw J1644+57) is thought to arise from the tidal disruption of a passing star by a dormant massive black hole.…
Reply to [arXiv:1105.5147] "Are GRB 090423 and Similar Bursts due to Superconducting Cosmic Strings?"
K. S. Cheng, Yun-Wei Yu, T. Harko
The GRB outflow driven by superconducting cosmic strings is likely to be an arc rather than a usually-considered spherical cap. In such a case, the afterglows of the cosmic string…
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 the Fermi Bubble
K. S. Cheng, D. O. Chernyshov, V. A. Dogiel +2
Fermi has discovered two giant gamma-ray-emitting bubbles that extend nearly 10kpc in diameter north and south of the galactic center (GC). The existence of the bubbles was first e…
