Thin-Shell Black Bounce
Leandro A. Lessa, Renan B. Magalhães, Gonzalo J. Olmo
A recently proposed class of black-bounce solutions sourced by anisotropic fluids, whose exterior reproduces the Reissner-Nordström geometry all the way down to a minimal-area boun…

Charged particles and fields in bumblebee gravity: Periodic orbits and superradiance
Marco A. A. de Paula, Renan B. Magalhães, V. B. Bezerra +1
We investigate the dynamics of charged particles and fields in the background of a charged black hole in bumblebee gravity, aiming to better understand the role played by the Loren…

Scattering by deformed black holes
Renan B. Magalhães, Luiz C. S. Leite, Luís C. B. Crispino
Obtaining black hole solutions in alternative theories of gravity can be a difficult task due to cumbersome field equations that arise in many of such theories. In order to study t…
