Study of Dynamical Instability of Collapsing Charged Spherically Symmetric Anisotropic Matter Configurations within Non-Minimally Coupled Gravity
A. Rehman, M. Yousaf, Mohammed Zakarya +2
We investigate the dynamical instability and gravitational collapse of charged, spherically symmetric anisotropic matter configurations within gravity. The a…
Magnetic Reconnection and Energy Extraction from a Rotating Black Hole in the Einstein-AdS SU(N)-Nonlinear Sigma Model
Muhammad Israr Aslam, Muhammad Nawaz, Abdul Malik Sultan +3
In the present study, we analyze the power and efficiency of energy extraction via magnetic reconnection in the rotating Einstein-AdS-SU()-NLSM black hole, both in the circular-…
Impact of a Cold Dark Matter Halo on Magnetic Reconnection and Energy Extraction from Kerr-like Black Holes
Muhammad Nawaz, Abdul Malik Sultan, Muhammad Israr Aslam +2
Recently, Comisso and Asenjo introduced a new energy extraction mechanism based on magnetic reconnection. In this paper, we investigate the power and efficiency of magnetic reconne…
Magnetic Reconnection and Energy Extraction from a Rotating Black Hole in a Four-dimensional Einstein-Gauss-Bonnet Gravity
Abdul Malik Sultan, Muhammad Israr Aslam, Muhammad Nawaz +4
Recently, Comisso and Asenjo proposed a new mechanism for energy extraction based on magnetic reconnection of plasma within the ergosphere. In this paper, we analyze the power and…
Optical Appearance of a Rotating Black Hole in Nonlinear Electrodynamics Surrounded by Thin Accretion Disks
Abdul Malik Sultan, Manahil Ali, Muhammad Israr Aslam +1
This work investigates the optical appearance of a rotating black hole (BH) in nonlinear electrodynamics (NED) using two illumination models, namely a celestial sphere and a thin a…
Repetitive Penrose Process in Rastall Rotating Black Holes Immersed in Quintessence Dark Energy
Ali Ahmad Sabir, Muhammad Israr Aslam, Abdul Malik Sultan +3
We investigate the repetitive Penrose process in the spacetime of a Rastall rotating black hole surrounded by a quintessence dark energy field. After reviewing the fundamental prop…
