Braneworlds in Einstein-Scalar-Gauss-Bonnet gravity
José Euclides G. Silva, Leandro A. Lessa, Roberto V. Maluf
We explore the features of a thick braneworld model in five dimensions governed by a Einstein-Gauss-Bonnet gravity with a non-minimal coupling to a dynamical scalar field. We consi…
Fermionic greybody factors and strong gravitational lensing by Lorentz-violating global monopole
F. M. Belchior, R. V. Maluf, A. R. M. Oliveira +2
In this work, we study the greybody factors (GFs) of spin 1/2 and spin 3/2 fermions for a black hole with global monopole in self-interacting Kalb-Ramond gravity with Lorentz symme…
Echoes and quasinormal modes of asymmetric black bounces
Alana C. L. Santos, Leandro A. Lessa, Roberto V. Maluf +1
We study quasinormal modes and echoes of symmetric and asymmetric black bounce solutions generated by anisotropic fluids within the framework of general relativity. We derive the e…
Regular black hole solutions in -dimensional gravity coupled to nonlinear electrodynamics
Miguel A. S. Pinto, Roberto V. Maluf, Gonzalo J. Olmo
In this paper, we investigate regular black hole solutions in the (2+1)-dimensional versions of General Relativity and gravity, both coupled to nonlinear electrodynamics.…
Perturbative solutions for compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics
R. V. Maluf, J. E. G. Silva, C. A. S. Almeida +1
We investigate the space-time geometry generated by compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics. Inspired by previous studies where the Bopp-Podolsky field a…
Global monopole in a Ricci-coupled Kalb-Ramond bumblebee gravity
F. M. Belchior, R. V. Maluf, A. Yu. Petrov +1
In this paper, we investigate black hole solutions in Einstein-Kalb-Ramond (EKR) bumblebee gravity sourced by a global monopole characterized by the charge . This modified theor…
