Spherically Symmetric Quantum-Corrected Black Holes with String Clouds: A Multi-Observable Analysis

Faizuddin Ahmed, Ahmad Al-Badaw, Orhan Donmez +4

We present an investigation of quantum-corrected black hole spacetimes coupled with clouds of strings, examining two distinct theoretical models that incorporate quantum gravitatio…

Analytic and Numerical Constraints on QPOs in EHT and XRB Sources Using Quantum-Corrected Black Holes

Ahmad Al-Badawi, Faizuddin Ahmed, Orhan Donmez +4

This investigation examines QPOs in two quantum-corrected BH spacetimes that preserve general covariance while incorporating quantum gravitational effects through a dimensionless p…
