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…

Dymnikova-Schwinger quantum-corrected slowly rotating wormholes: Photon and spinning particle dynamics

A. Errehymy, Y. Khedif, M. Daoud +3

This work studies light propagation near slowly rotating traversable wormholes supported by a quantum-inspired matter source. The model is based on the Dymnikova density profile, v…

Event Horizon Telescope Observational Constraints on Dymnikova-Type Non-Singular Black Holes in Higher Dimensions

A. Errehymy, Y. Khedif, M. Daoud +3

Black holes are among the most compelling predictions of general relativity (GR) and are now strongly supported by observations from gravitational-wave detectors and the Event Hori…

Quantum corrections to Dymnikova-Schwinger black holes in Einstein-Gauss-Bonnet gravity

A. Errehymy, Y. Khedif, M. Daoud +3

This work investigates black holes within a modified framework of gravity that incorporates quantum-inspired corrections and a fundamental minimal length scale. By integrating Eins…
