QPO-like Signatures and Hydrodynamical Variability in Accretion around a JNW-type Compact Spacetime in Freund-Nambu Scalar-Tensor Gravity
Orhan Donmez, M. Yousaf, G. Mustafa
Scalar tensor theories of gravity provide a broad as well as physically rich extension of general theory of relativity by allowing the gravitational interaction to be mediated not…

Accretion flow around Kerr metric in the infra-red limit of asymptotically safe gravity
Orhan Donmez, Sushant G. Ghosh, M. Yousaf +2
We investigate accretion disk dynamics and the formation of quasi-periodic oscillations (QPOs) in the infrared limit around Kerr-like black holes in asymptotically safe gravity. Re…
