Quasinormal modes and excitation factors of a regular black hole with zero-point length
Milena Skvortsova
We study the ringdown of the regular Jusufi-Singleton black hole, whose nonsingular core is controlled by a zero-point length arising from a non-local, T-duality-inspired gravitati…

Hawking Radiation from the Dymnikova Regular Black Hole
Milena Skvortsova
We study Hawking radiation of the Dymnikova regular black hole. This model replaces the central singularity by a smooth de Sitter core while remaining Schwarzschild-like far from t…

Massive scalar quasinormal modes of an asymptotically flat regular black hole supported by a phantom Dirac--Born--Infeld field
Milena Skvortsova
We study the quasinormal spectrum of a massive test scalar field in the exact asymptotically flat regular black-hole geometry supported by a phantom Dirac--Born--Infeld scalar. Usi…
