Non-Schwarzschild black holes sourced by scalar-vector fields
Manuel Gonzalez-Espinoza, Y. Gómez-Leyton, Z. Stuchlik +1
In this work, we construct a static and spherically symmetric black hole solution sourced by a nonlinear scalar-vector sector within the framework of the Minimal Geometric Deformat…
Carter-constant induced mechanism for generation of anisotropic kinetic equilibria in collisionless N-body systems
Claudio Cremaschini, Zdeněk Stuchlík
A new intrinsically-relativistic kinetic mechanism for generation of non-isotropic relativistic kinetic equilibria in collisionless N-body systems is pointed out. The theory is dev…
Adiabatic theory in Kerr spacetimes
Kuantay Boshkayev, Gulmira Nurbakyt, Hernando Quevedo +7
We present the main aspects of the adiabatic theory and show that it can be used to study the motion of test particles in general relativity. The theory is based upon the use of ve…
A causal Schwarzschild-de Sitter interior solution by gravitational decoupling
L. Gabbanelli, J. Ovalle, A. Sotomayor +2
We employ the minimal geometric deformation approach to gravitational decoupling (MGD- decoupling) in order to build an exact anisotropic version of the Schwarzschild interior solu…
Exact solution for a black hole embedded in a nonstatic dust-filled universe
Elena Kopteva, Pavlina Jaluvkova, Irina Bormotova +1
An exact solution of the Lemaître--Tolman--Bondi class is investigated as a possible model of the Schwarzschild-like black hole embedded in a non-static dust-filled universe for th…
Scalar perturbations of nonsingular nonrotating black holes in conformal gravity
Bobir Toshmatov, Cosimo Bambi, Bobomurat Ahmedov +2
We study scalar and electromagnetic perturbations of a family of nonsingular nonrotating black hole spacetimes that are solutions in a large class of conformally invariant theories…
The generalized Lemaitre-Tolman-Bondi solutions with nonzero pressure in modeling the cosmological black holes
E. Kopteva, P. Jaluvkova, Z. Stuchlik
In this work we have obtained the set of new exact solutions of the Einstein equations that generalize the known Lemaitre-Tolman-Bondi solution for the certain case of nonzero pres…
General relativistic polytropes with a repulsive cosmological constant
Zdeněk Stuchlík, Stanislav Hledík, Jan Novotný
Spherically symmetric equilibrium configurations of perfect fluid obeying a polytropic equation of state are studied in spacetimes with a repulsive cosmological constant. The confi…
Efficiency of the Keplerian accretion in the Braneworld Kerr--Newman Spacetimes and mining instability of some naked singularity spacetimes
Martin Blaschke, Zdeněk Stuchlík
We show that the~braneworld rotating Kerr--Newman black hole and naked singularity spacetimes with both positive and negative braneworld tidal charge parameter can be separated int…
The model of the black hole enclosed in dust. The flat space case
Pavlina Jaluvkova, Elena Kopteva, Zdenek Stuchlik
In this work the model is constructed to describe the black hole enclosed in the dust cosmological background in case of zero spatial curvature. This model is based on our exact so…
Shadow of the rotating black hole with quintessential energy in the presence of the plasma
Ahmadjon Abdujabbarov, Bobir Toshmatov, Zdeněk Stuchlík +1
We study the shadow of the rotating black hole with quintessential energy i) in vacuum and ii) in the presence of plasma with radial power-law density. For vacuum case the quintess…
The Aschenbach effect: unexpected topology changes in motion of particles and fluids orbiting rapidly rotating Kerr black holes
Z. Stuchlik, P. Slany, G. Torok +1
Newton's theory predicts that the velocity of free test particles on circular orbits around a spherical gravity center is a decreasing function of the orbital radius , $dV/d…
