Observational Constraints on Kazakov-Solodukhin Quantum-Deformed Black Holes from M87 and Sgr A Shadows
A. Errehymy, Y. Khedif, M. Daoud +4
We explore the Kazakov-Solodukhin quantum-deformed black hole spacetime, characterized by a single deformation parameter \( η\) that encodes quantum corrections to the classical S…

Slowly rotating traversable wormholes supported by radially varying string-fluid matter: From regular geometries to photon trajectories
A. Errehymy, B. Turimov, M. A. Khan +3
This work investigates slowly rotating traversable wormholes supported by string fluids whose properties vary with distance from the throat. This radial variation allows the matter…

Dark Energy Stars in Rastall-Rainbow Gravity: Structure, Stability and Observational Constraints
Ayan Banerjee, Bobur Turimov, Sulton Usanov +3
In this work, we investigate static configurations of dark energy stars within the framework of Rastall-Rainbow (R-R) gravity, which combines an energy-dependent deformation of spa…
