Particle dynamics in non-rotating Konoplya and Zhidenko black hole immersed in an external uniform magnetic field
Aqeela Razzaq, Rehana Rahim
In this paper, we investigate the dynamics of particles in the background of non-rotating Konoplya and Zhidenko black hole that is immersed in an external uniform magnetic field. T…

Charging the Johannsen-Psaltis spacetime
Rehana Rahim, Khalid Saifullah
In this paper we develop the charged version of the spacetime proposed by Johannsen and Psaltis. Rotation is introduced in the deformed Reissner-Nordström spacetime by complex coor…

The marginally trapped surfaces in spheroidal spacetimes
Rehana Rahim, Andrea Giusti, Roberto Casadio
We study the location of marginally trapped surfaces in space-times resulting from an axial deformation of static isotropic systems, and show that the Misner-Sharp mass evaluated o…
