Observational Constraints on Kazakov-Solodukhin Quantum-Deformed Black Holes from M87${}^{\ast }$ and Sgr A${}^{\ast }$ 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…
