Retrolensing by a spherically symmetric naked singularity
Gulmina Zaman Babar, Farruh Atamurotov, Abdullah Zaman Babar +1
Considering a strong field limit, we investigate the retrolensing phenomenon in the vicinity of a Janis-Newman-Winicour (JNW) naked singularity embedded in a scalar field. We assum…
Particle acceleration around rotating Einstein-Born-Infeld black hole and plasma effect on gravitational lensing
Gulmina Zaman Babar, Farruh Atamurotov, Shafqat Ul Islam +1
We consider a time-like geodesics in the background of rotating Einstein-Born-Infeld (EBI) black hole to examine the horizon and ergosphere structure. The effective potential that…
Gravitational lensing in 4-D Einstein-Gauss-Bonnet gravity in the presence of plasma
Gulmina Zaman Babar, Farruh Atamurotov, Abdullah Zaman Babar
In this paper we have assumed a weak-field regime to explore the gravitational lensed photons in a 4 dimensional Einstein-Gauss-Bonnet gravity, which is very much in the limelight…
Optical properties of Kerr-Newman spacetime in the presence of plasma
Gulmina Zaman Babar, Abdullah Zaman Babar, Farruh Atamurotov
We have studied the null geodesics in the background of the Kerr-Newman black hole veiled by a plasma medium using the Hamilton-Jacobi method. The in uence of black hole's charge a…
Periodic orbits around a spherically symmetric naked singularity
Gulmina Zaman Babar, Adil Zaman Babar, Yen-Kheng Lim
The motion of time-like test particles in the Fisher/Janis-Newman-Winicour (F/JNW) spacetime is studied with the Hamiltonian formulation of the geodesic equations. The spacetime is…
Dynamics of a charged particle around a weakly magnetized naked singularity
Gulmina Zaman Babar, Mubasher Jamil, Yen-Kheng Lim
We examine the motion of a charged particle in the vicinity of a weakly magnetized naked singularity. The escape velocity and energy of the particle moving around the naked singula…
