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…

Estimating the possible QPOs of M87* from the parameters of a hairy Kerr black hole
Orhan Donmez, Fatih Dogan
In this paper, we study the dynamics of the shock cone formed around the hairy Kerr black hole due to BHL accretion and investigate the QPO behaviors resulting from the black hole-…
