Shock acceleration in vortex driven magnetic fields of black holes
Zaza N. Osmanov
The aim of this work is to investigate particle acceleration by shock waves in the magnetospheres of supermassive black holes, where the magnetic field is vortex-driven. For this p…
Modified light-cylinder and centrifugal acceleration in Schwarzschild geometry
Nikoloz Kurtskhalia, Nikolai Maltsev, Zaza N. Osmanov
We examine the motion of an electron constrained to follow a magnetic field line near a primordial sub-stellar mass black hole. Earlier studies treated the problem in flat (Minkows…
Megastructures of type-III civilizations orbiting galaxies
Zaza N. Osmanov
The article discusses the possibility of a Type-III extraterrestrial civilization constructing megastructures around a galaxy in regions where the galactic radiation becomes indist…
Vortex driven Schwinger pair creation in the magnetosphere of SgrA*
Zaza N. Osmanov
In this work, we explore the possibility of Schwinger pair creation triggered by magneto-centrifugal effects in the magnetosphere of SgrA*. We show that these effects become extrem…
Can the solar atmosphere generate very high energy cosmic rays?
Z. N. Osmanov, D. Kuridze, S. M. Mahajan
The origin and acceleration of high-energy particles in space (cosmic rays), constitute important topics in modern astrophysics. Among the The origin and acceleration of high-energ…
Pair creation in the vortex-driven magnetic fields of black holes
Zaza N. Osmanov
We study the effects of pair creation on the radiation emerging from black holes under the assumption that the magnetic fields are vortex driven. In particular, for a sufficiently…
The possibility for panspermia in the galaxy by means of planetary dust grains
Z. N. Osmanov
By obtaining the assumption that planetary dust particles can escape from the gravitational attraction of a planet, we consider the possibility for the dust grains to leave the sta…
