Orbital, Shadow, and Thin-Disk Signatures of a Regular Black Hole with Gravitational Self-Energy
Erdinç UlaŠSaka
We investigate geodesic motion, shadow observables and thin-disk accretion for the regular black hole generated by a non-local gravitational self-energy contribution. The geometry…

Gravitational quasinormal modes of Dymnikova black holes
Bekir Can LütfüoÄlu, Erdinç UlaÅ Saka, Abubakir Shermatov +3
We investigate gravitational quasinormal modes of the Dymnikova black hole, a regular spacetime in which the central singularity is replaced by a de Sitter core. This geometry, ori…

Proper-Time Approach in Asymptotic Safety via Black Hole Quasinormal Modes and Grey-body Factors
Bekir Can LütfüoÄlu, Erdinç UlaÅ Saka, Abubakir Shermatov +3
We study the quasinormal mode spectrum and grey-body factors of black holes in an effectively quantum-corrected spacetime, focusing on the influence of near-horizon modifications o…
