Multi-wavelength Emission from the Fermi Bubble II. Secondary Electrons and the Hadronic Model of the Bubble
K. -S. Cheng, D. O. Chernyshov, V. A. Dogiel +1
We analyse the origin of the gamma-ray flux from the Fermi Bubbles (FBs) in the framework of the hadronic model in which gamma-rays are produced by collisions of relativistic proto…
On the Origin of the 6.4 keV Line in the Galactic Center Region
V. A. Dogiel, D. O. Chernyshov, A. M. Kiselev +1
We analyse the 6.4 keV iron line component produced in the Galactic Center (GC) region by cosmic rays in dense molecular clouds (MCs) and in the diffuse molecular gas. We showed th…
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…
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…
