Kinematic Bounds on Charged Energy Extraction in the Purely Electric Branch of Euler--Heisenberg Type f(R,T) Black Holes
Anirudh Pradhan, K. Ghaderi, M. Zeyauddin
We derive and test kinematic upper bounds on charged energy extraction in the purely electric branch of a static black hole family sourced by an Euler--Heisenberg type non…
Charged Penrose Extraction in RN--AdS Black Holes with Dark Energy: Ergosphere Geometry and Rigorous Efficiency Bounds
Anirudh Pradhan, K. Ghaderi, M. Zeyauddin
We develop a quantitative framework for charge assisted Penrose extraction in Reissner--Nordström Anti-de Sitter black holes surrounded by a Kiselev type anisotropic dark energy se…
Coupled Gravitoelectromagnetic Response of a Magnetically Supported Generalized Hayward Black Hole in Nonlinear Electrodynamics
Anirudh Pradhan, K. Ghaderi, M. Zeyauddin +1
We construct the exterior coupled gravitational and electromagnetic response of a magnetically supported generalized Hayward black hole within a specified nonlinear electrodynamic…
Finite mass two throat wormholes: global light rings, branch resolved strong lensing, and scalar transmission
Anirudh Pradhan, K. Ghaderi, M. Zeyauddin +1
We introduce a static, horizonless, asymptotically flat two throat wormhole family in which one global metric determines the geometry, effective source, null dynamics, lensing, and…
Particle Creation and Variable Generalized Chaplygin Gas in Gravity
N. Myrzakulov, S. H. Shekh, Anirudh Pradhan +1
In this work, we investigate the cosmological dynamics of a spatially flat Friedmann--Lemaître--Robertson--Walker Universe in the framework of generalized \( \mathcal{F}(\mathcal{…
Anisotropic Cosmology with interacting Dark Energy in f(R,T) Gravity: A Data-Constrained & independent Approach
S. H. Shekh, N. Myrzakulov, Anirudh Pradhan +1
In this work, we investigate the cosmological dynamics of an anisotropic Universe within the framework of gravity by incorporating pressureless dark matter and the dark en…
