Schwarzschild black hole as accelerator of accelerated particles
O. B. Zaslavskii
We consider collision of two particles near the horizon of a nonextremal static black hole. At least one of them is accelerated. We show that the energy in the center of…
Redshift/blueshift inside the Schwarzschild black hole
O. B. Zaslavskii
We consider an observer who moves under the horizon of the Schwarzschild black hole and absorbs a photon. There are two different situations when (i) a photon comes from infinity,…
On strategies of motion under the black hole horizon
A. V. Toporensky, O. B. Zaslavskii
In this methodological paper we consider two problems an astronaut faces with under the black hole horizon in the Schwarzschild metric. 1) How to maximize the survival proper time.…
Center of mass energy of colliding electrically neutral particles and super-Penrose process
O. B. Zaslavskii
We consider collisions of electrically neutral particles in the background of axially symmetric rotating space-times. For reactions of the kind 1+23+4 we give full…
Extraction of energy from an extremal rotating electrovacuum black hole: Particle collisions along the axis of symmetry
F. Hejda, J. Bičák, O. B. Zaslavskii
High-energy collisions can occur for radially moving charged test particles in the extremal Reissner-Nordström spacetime if one of the particles is fine-tuned and the collision poi…
