Full set of scenarios of high energy collision in the Schwarzschild background and kinematic censorship

A. V. Toporensky, P. Gusin, A. Radosz +1

We consider collisions between particles moving freely in the Schwarzschild background. We suggest classification of scenarios that lead to unbounded energy output in the center of…

Recursive Penrose processes in electrically charged black hole spacetimes: Backreaction and energy extraction

Duarte Feiteira, José P. S. Lemos, Oleg B. Zaslavskii

We study a recursive Penrose process and the energy extraction for the decay of electrically charged particles in a Reissner-Nordström black hole spacetime with anti-de Sitter (AdS…

High energy particle collisions under Cauchy horizon

A. V. Toporensky, O. B. Zaslavskii

We consider particle collision inside the inner horizon of the Reissner-Nordstrom metric in the so-called R region. We show that there exist scenario in which the enrgy in the cent…

Circular orbits in spherically symmetric spacetimes and BSW effect with nonzero force

Hryhorii Ovcharenko, O. B. Zaslavskii

We consider circular particle motion under the action of an unspecified force in a static spherically symmetric spacetime. We derive the machinery that allows one to find the force…

Generalized Lemaître time for rotating and charged black holes and its near-horizon properties

A. V. Toporensky, O. B. Zaslavskii

We consider the behavior of the analogue of the Lemaitre time when a particle approaches the horizon of a rotating black hole. For the Kerr metric, the aforementioned time coincide…

Inverted equation of state and general approach to vacuum-like configurations

O. B. Zaslavskii

We consider spherically symmetric static black hole configurations that obey the vacuum equation of state: , where is the radial pressure, being energy densit…
