Vectorial and spinorial perturbations in Galileon Black Holes: Quasinormal modes, quasiresonant modes and stability
E. Abdalla, B. Cuadros-Melgar, Jeferson de Oliveira +2
In this work we have considered a model that includes the interaction of gravity and matter fields with Galilean invariance (the so-called derivative coupling) as well as some corr…
Dynamical evolution of non-minimally coupled scalar field in spherically symmetric de Sitter spacetimes
R. D. B. Fontana, Jeferson de Oliveira, A. B. Pavan
We investigate the dynamical behavior of a scalar field non-minimally coupled to Einstein's tensor and Ricci scalar in geometries of asymptotically de Sitter spacetimes. We show th…
Three-dimensional black holes with quintessence
Jeferson de Oliveira, R. D. B. Fontana
We study a quintessential black hole solution in three dimensions, with mass and quintessence charge. By exploring the Carter-Penrose diagram, we show the presence of spacelike and…
