Late-Time Cosmological Tests of a Minisuperspace Generalized-Uncertainty-Principle Deformation
G. G. L. Nashed
The paper examines how a quadratic generalized‑uncertainty‑principle deformation of the FLRW minisuperspace alters the Friedmann equation and uses late‑time observational data (cos…
Rotating traversable wormholes and particle dynamics in gravity
G. G. L. Nashed, Waleed El Hanafy, Amare Abebe +2
Traversable wormholes are among the most interesting solutions of gravitational theories, but within General Relativity they generally require exotic matter violating the null ener…
Photon Sphere and Shadow of a Perturbative Black Hole in Gravity
G. G. L. Nashed
We investigate the impact of higher-curvature corrections on black-hole observables within a perturbative gravity framework. Working in a static, spherically symmetric sp…
Light Deflection and Greybody Bound Around a BTZ-ModMax Black Hole in Plasma Medium
Ritesh Pandey, Shubham Kala, Amare Abebe +2
We study the deflection of light in a homogeneous plasma medium around a BTZ-ModMax black hole, focusing on the effects of the ModMax nonlinear electrodynamics parameter and the co…
