Perturbations and quasinormal modes of black holes in general relativity coupled to nonlinear electrodynamics
Uktamjon Uktamov, Bakhtiyor Narzilloev, Ibrar Hussain +2
We investigate the quasinormal spectra and time-domain evolution of scalar, electromagnetic, and gravitational perturbations of the Einstein-Bronnikov black hole in Einstein gravit…
Low-mass X-ray binaries as a probe of Kerr-MOG black hole spacetime
Bakhodirkhon Saidov, Bakhtiyor Narzilloev, Ibrar Hussain +1
We investigate the astrophysical implications of rotating black holes in modified gravity by studying the Kerr-MOG spacetime and applying it to several stellar-mass black hole cand…
Long-lived quasinormal modes and asymptotic tails of regular Schwarzschild-like black holes in the presence of a magnetic field
Akbar Davlataliev, Bakhtiyor Narzilloev, Ibrar Hussain +2
We analyze the evolution of perturbations of a (charged) massive scalar field near a regular Simpson-Visser black hole, allowing for a non-zero external magnetic field. We show tha…
Probing black hole in Starobinsky-Bel-Robinson gravity with thermodynamical analysis, effective force and gravitational weak lensing
G. Mustafa, Allah Ditta, Faisal Javed +3
In this work, we investigate the effects of plasma and the coupling parameter , on the thermodynamic properties and weak gravitational lensing by the Schwarzschild-like black…
