Long-lived ringing of Bronnikov--Kim brane-world black holes and wormholes
Milena Skvortsova
Massive-field perturbations on black-hole and wormhole backgrounds can form long-lived quasinormal ringing; this behaviour is not confined to brane-world spacetimes, but it is also…
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…

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…
