Quasinormal modes of a quantum inspired black hole in four dimensions with cosmological constant
R. D. B. Fontana, Jeferson de Oliveira, B. Eslam Panah +1
We study the scalar and Dirac perturbations of quantum-corrected black holes with cosmological constant. Using two different methods (WKB and double-null characteristic integration…

Causal structure of black holes immersed in a Chaplygin-like dark fluid environment: Horizons and singularities
Rodrigo Dal Bosco Fontana, Jeferson de Oliveira
In the present work, we study the causal structure of spherically symmetric black holes immersed in a Chaplygin-like dark fluid, emphasizing the impact of the fluid parameters on c…

Lower dimensional black holes in nonlinear electrodynamics: causal structure and scalar perturbations
Rodrigo Dal Bosco Fontana
We study the charged black hole solutions of a 2+1 nonlinear electrodynamical theory with cosmological constant. Considered as a one-parameter group of theories (the exponent of th…
