Regular Vaidya solutions of effective gravitational theories
Valentin Boyanov, Raúl Carballo-Rubio
We initiate the study of the dynamics of spherically symmetric spacetimes beyond general relativity through exact solutions of the field equations of second-order effective gravita…
Semiclassical evolution of a dynamically formed spherical black hole with an inner horizon
Valentin Boyanov, David Hilditch, Artur Semião
In this work we obtain a numerical self-consistent spherical solution of the semiclassical Einstein equations representing the evaporation of a trapped region which initially has b…
Towards a Non-singular Paradigm of Black Hole Physics
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18
The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…
On destabilising quasi-normal modes with a radially concentrated perturbation
Valentin Boyanov
In this work we explore some aspects of the spectral instability of back hole quasi-normal modes, using a specific model as an example. The model is that of a small bump perturbati…
The dynamical response of viscous objects to gravitational waves
Valentin Boyanov, Vitor Cardoso, Kostas D. Kokkotas +1
We study the dynamical response of viscous materials to gravitational waves, in the context of a fully relativistic theory of fluid dynamics. For the first time, we calculate oscil…
