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…

Optical features of rotating quintessential charged black holes in de-Sitter spacetime
Saeed Ullah Khan, Javlon Rayimbaev, Furkat Sarikulov +1
One of the most important and actual issues in relativistic astrophysics is testing gravity theories and obtaining constraint values for the parameters of black holes using observa…

Quasiperiodic oscillations around hairy black holes in Horndeski gravity
Javlon Rayimbaev, Konstantinos F. Dialektopoulos, Furkat Sarikulov +1
Testing gravity theories and their parameters using observations is an important issue in relativistic astrophysics. In this context, we investigate the motion of test particles an…
