Gravitational decoupling and regular hairy black holes: Geodesic stability, quasinormal modes, and thermodynamic properties
R. C. de Paiva, K. S. Alves, R. T. Cavalcanti +1
The stability of geodesic orbits around a regular hairy black hole, in the gravitational decoupling setup, is investigated by employing Lyapunov exponents, which quantify the diver…
Hair imprints of the gravitational decoupling and hairy black hole spectroscopy
V. F. Guimarães, R. T. Cavalcanti, R. da Rocha
Hairy black holes by gravitational decoupling (GD) are probed to derive the gravitational waveform produced by perturbation theory applied to these compact objects. Using the Regge…
Black Holes with a charged quantum dust core
R. Casadio, R. da Rocha, A. Giusti +1
To understand the nature of the black holes that exist in the Universe, it is also necessary to study what happens to the (quantum) matter that collapses and forms such objects. In…
When gravitational decoupling and quantum gravity (re)unite
R. Casadio, I. Kuntz, R. da Rocha
The effective action for quantum gravity coupled to matter contains corrections arising from the functional measure. We analyse the effect of such corrections for anisotropic self-…
Gravitational decoupling and aerodynamics: black holes and analog gravity in a jet propulsion lab
R. Casadio, C. Noberto Souza, R. da Rocha
A connection is established between transonic sound waves propagating along a de Laval nozzle and quasinormal modes emitted from hairy black holes obtained with the gravitational d…
Quantum hair and entropy for slowly rotating quantum black holes
Wenbin Feng, Roldao da Rocha, Roberto Casadio
We study the quantum hair associated with coherent states describing slowly rotating black holes and show how it can be naturally related with the Bekenstein-Hawking entropy and wi…
