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…
Extracting Energy from a Non-Kerr Rotating Spacetime with an Anomalous Quadrupole Moment via Magnetic Reconnection
Ke Wang, Xiao-Xiong Zeng
This paper investigates how to extract energy from a non-Kerr rotating spacetime with an anomalous quadrupole moment via the magnetic reconnection mechanism. Unlike many other rota…
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…
Particle decay and energy conservation in the Kerr-Newman black hole
Bing-Bing Chen, Guo-Ping Li, Ke Wang +1
The paper investigates how a particle decays in Kerr‑Newman black hole spacetime, showing that the mass loss of the parent particle is converted into kinetic energy and analyzing h…
