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…
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 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…
