Simulations of black hole accretion torus in various magnetic field configurations
Martin Kološ, Agnieszka Janiuk
Using axisymetric general relativistic magnetohydrodynamics simulations we study evolution of accretion torus around black hole endowed with different initial magnetic field config…
Axially symmetric and static solutions of Einstein equations with self-gravitating scalar field
Bobur Turimov, Bobomurat Ahmedov, Martin Kološ +1
The exact axisymmetric and static solution of the Einstein equations coupled to axisymmetric and static gravitating scalar (or phantom) field is presented. The spacetimes modified…
Orbital widening due to radiation reaction around a magnetized black hole
Arman Tursunov, Martin Kološ, Zdeněk Stuchlík
Radiation reaction acting on a charged particle moving at a stable circular orbit of a magnetized black hole can lead to the shift of the orbital radius outwards from the black hol…
Mass of intermediate black hole in the source M82 X-1 restricted by models of twin high-frequency quasi-periodic oscillations
Zdeněk Stuchlík, Martin Kološ
We apply the relativistic precession (RP) model with its variants and the resonance epicyclic model with its variants, based on the frequencies of the geodesic epicyclic motion in…
Current-carrying string loops in black-hole spacetimes with a repulsive cosmological constant
Martin Kološ, Zdeněk Stuchlík
Current-carrying string loop dynamics in Schwarzschild-de Sitter spacetimes characterized by the cosmological parameter λ=1/3ΛM^2 is investigated. With attention concentrated to th…
