Sourced Gravitational Radiation in Parity-Violating Tetrad Gravity
G. G. L. Nashed
We study linear gravitational modes, sourced far-zone fields, and quadratic energy balance in a four-parameter tetrad theory of gravity. The theory contains three parity-even torsi…
Electrically Charged Distorted Black Holes: Thermodynamics, Particle Dynamics, and Quasinormal Signatures
Gamal G. L. Nashed, Salvatore Capozziello
We construct an exact solution for the electrically charged extension of a distorted black hole spacetime within Einstein-Maxwell theory using the Harrison transformation. The resu…
Analytic semiclassical backreaction of a Schwarzschild black hole in a finite cavity: horizon shift, temperature renormalization, and canonical stability in the Hartle-Hawking State
G. G. L. Nashed, Alnadhief H. A. Alfedeel, Tiberiu Harko
We construct an analytic model of static semiclassical backreaction for a Schwarzschild black hole in the Hartle--Hawking state enclosed within a finite spherical cavity. Using a m…
A Minimal and Stable Vacuum Bounce in Exponential Gravity
G. G. L. Nashed, A. Eid
We investigate the realization of a nonsingular cosmological bounce in metric gravity using a controlled exponential deformation of the Starobinsky model. Adopting a…
Black Hole Topologies and Geodesic Structures in Symmetric Teleparallel f(Q) Gravity
G. G. L. Nashed, A. Eid
Black hole solutions are studied here within the symmetric teleparallel formulation of gravity, employing the model in which the gravitational dynamics are governed by the n…
Holographic Dark Energy as a Source for Wormholes in Modified Gravity
G. G. L. Nashed, A. Eid
Traversable wormhole solutions are explored in gravity, a curvature--matter extension in which is the Ricci scalar and denote…
