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…

Gravitational synchrotron radiation and Penrose process in STVG theory

Bobur Turimov, Husan Alibekov, Pulat Tadjimuratov +1

The paper has explored analogue of gravitational synchrotron massive particle and Penrose process in MOdified Gravity (MOG) known as Scalar-Tensor-Vector-Gravity (STVG). Investigat…

Probing Geometric Proca in Metric-Palatini Gravity with Black Hole Shadow and Photon Motion

Elham Ghorani, Beyhan Puliçe, Farruh Atamurotov +3

Extended metric-Palatini gravity, quadratic in the antisymmetric part of the affine curvature, is known to lead to the general relativity plus a geometric Proca field. The geometri…

Overcharging process around a magnetized black hole: Can the backreaction effect of magnetic field restore cosmic censorship conjecture?

Sanjar Shaymatov, Bobomurat Ahmedov

It is well known that the electrically charged Reissner-Nordström black hole could be overcharged. Here, we investigate the process of overcharging of a magnetized Reissner-Nordstr…

Shadow and quasinormal modes of the Kerr-Newman-Kiselev-Letelier black hole

Farruh Atamurotov, Ibrar Hussain, G. Mustafa +1

We investigate the null geodesics and the shadow cast by the Kerr-Newman-Kiselev-Letelier (KNKL) black hole for the equation of state parameter and for different values…

Shadows and gravitational weak lensing by the Schwarzschild black hole in the string cloud background with quintessential field

Ghulam Mustafa, Farruh Atamurotov, Ibrar Hussain +2

In this work, we observe that in the presence of the string cloud parameter and the quintessence parameter , with the equation of state parameter the radius o…
