Dark matter effect on black hole accretion disks
D. Pugliese, Z. Stuchlík
Comparing different dark matter (DM) models, we explore the DM influence on black hole (BH) accretion disk physics, considering corotating and counterrotating thick accretion tori…
On photons and matter inversion spheres from complex super-spinars accretion structures
D. Pugliese, Z. Stuchlik
Our analysis focus on the dragging effects on the accretion flows and jet emission in Kerr super-spinars. These attractors are characterized by peculiar accretion structures as dou…
Shadow of novel rotating black holes in GR coupled to nonlinear electrodynamics and constraints from EHT results
Muhammad Ali Raza, Furkat Sarikulov, Javlon Rayimbaev +3
We study the optical properties of spacetime around a novel regular black hole (BH) in general relativity (GR) coupled to nonlinear electrodynamics (NED), which is asymptotically f…
Testing alternative spacetimes by high-frequency quasi-periodic oscillations observed in microquasars and active galactic nuclei
Misbah Shahzadi, Martin Kološ, Rabia Saleem +1
In this article, we try to capture the influence of deviation from standard Kerr black hole spacetime on observed high-frequency quasi-periodic oscillations signal. We explore the…
Kinetic formulation of Tolman-Ehrenfest effect: Non-ideal fluids in Schwarzschild and Kerr space-times
Claudio Cremaschini, Jiří Kovář, Zdeněk Stuchlík +1
A review of the original thermodynamic formulation of the Tolman-Ehrenfest effect prescribing the temperature profile of uncharged fluid at thermal equilibrium forming stationary c…
Covariant formulation of spatially non-symmetric kinetic equilibria in magnetized astrophysical plasmas
Claudio Cremaschini, Massimo Tessarotto, Zdeněk Stuchlík
Astrophysical plasmas in the surrounding of compact objects and subject to intense gravitational and electromagnetic fields are believed to give rise to relativistic regimes. Theor…
