Proper-Time Approach in Asymptotic Safety via Black Hole Quasinormal Modes and Grey-body Factors
Bekir Can Lütfüoğlu, Erdinç Ulaş 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…

Gravitational quasinormal modes of Dymnikova black holes
Bekir Can Lütfüoğlu, Erdinç Ulaş 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…
