Did we already observe small mass black holes from the Galactic Center? |
The center of our Galaxy provides a uniquely accessible laboratory may be better than ground man-made. The most intense line of our Galaxy is coming also from Galactic Center: the 511 keV annihilation line. We study a possibility of pair creation due to X-ray and γ− photon interaction inside the compact Galactic Center SGR A shell. One of the possible origins for MeV-emission is a disk emission from mass accretion by SMall Mass Black Holes (SMMBHs). The X-rays generated in the GC interact with the ∼ 10 MeV temperature black-body emission from 10**17 g black-holes and produce e+e− pairs. We will also address the problem of dark matter related to the existence of small mass black holes. |
