Periodic Orbits and Their Gravitational-Wave Signatures around a Rotating Black Hole Surrounded by Perfect Fluid Dark Matter
M. R. Shahzad, Hamza Rehman, Saddam Hussain +1
We investigate equatorial timelike motion of a massive test particle and the associated gravitational radiation around a Kerr black hole surrounded by perfect fluid dark matter. In…
Probing Kerr black hole in a uniform Bertotti-Robinson magnetic field through astrophysical quasi-periodic oscillations
Hamza Rehman, Sanjar Shaymatov, Saddam Hussain +1
In this study, the behavior of high-frequency quasi-periodic oscillations (QPOs) is investigated around a Kerr black hole immersed in a uniform Bertotti-Robinson magnetic field. Th…
Epicyclic motion and accretion disk around a charged black hole in Einstein-ModMax theory with a quintessence field
Hamza Rehman, Sanjar Shaymatov, Tao Zhu
We investigate the epicyclic motion of charged test particles and the associated quasi-periodic oscillations (QPOs) around a weakly magnetized black hole surrounded by quintessence…
Exploring the accelerating black holes from the observations of quasi-periodic oscillations in X-ray binaries
Hamza Rehman, Saddam Hussain, G. Abbas +1
Black holes in dense astrophysical environments, such as globular clusters or in the vicinity of other massive objects, may possess accelerations. Such acceleration would modulate…
Constraints on extra charges in dyonic Kerr-Newman-Kasuya-Taub-NUT black hole from the observations of quasi-periodic oscillations
Hamza Rehman, Saddam Hussain, Ghulam Abbas +1
This paper investigates the influence of the dimensionless electric charge (), magnetic charge (), and Taub-NUT parameter () of a dyonic Kerr-Newman-Kasuya-Taub-NUT…
Accretion disk around Reissner-Nordström black hole coupled with a nonlinear electrodynamics field
G. Abbas, H. Rehman, Tao Zhu +2
The phenomenon by which matter accumulates in the vicinity of a huge celestial object is known as accretion. The gravitational energy is excreted as a consequence of infalling matt…
Analysis of accretion disk around the Euler-Heisenberg Anti-de Sitter Black Hole
G. Abbas, H. Rehman
We demonstrate the investigation of thin accretion disc surrounding the Einstein- Euler-Heisenberg-Anti-de Sitter black hole. Additionally, we analyze the black hole event horizons…
Matter accretion onto the magnetically charged Euler-Heisenberg black hole with scalar hair
H. Rehman, G. Abbas, Tao Zhu +1
This paper deals with astrophysical accretion onto the magnetically charged Euler-Heisenberg black holes with scalar hair. We examine the accretion process of a variety of perfect…
Accretion disc around black hole in Einstein- non-linear sigma model
G. Abbas, Hamza Rehman, M. Usama +1
The accretion of matter onto celestial bodies like black holes and neutron stars is a natural phenomenon that releases up to of the matter's rest-mass energy, which is consi…
