Ringdown and greybody signatures of rational regular black holes in non-polynomial gravity
Shohzod Jumaniyozov, Javlon Rayimbaev, Azam Payzullaev +3
We study the quasinormal mode spectrum and wave-scattering properties of the four-dimensional rational regular black hole recently obtained in non-polynomial (quasi-topological) gr…

Probing black holes surrounded by Dust field in Quantum Fluctuation Modified Gravity with twin-peak QPOs
Kamola Shermatova, Qodir Badalov, Abubakir Shermatov +5
We study a static, spherically symmetric black hole solution surrounded by a dust field within quantum fluctuation modified gravity, in which the quantum-fluctuation parameter …
