Shadow structure of generalized black-bounce metrics
Jose R. Nascimento, Ana R. M. Oliveira, Albert Yu. Petrov +2
The existence of black hole shadows is one of the most interesting effects of the strong field regime of general relativity (GR). Recent observations by the Event Horizon Telescope…
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…
Gravitational lensing by generalized black-bounce space-times
C. Furtado, A. L. A. Moreira, J. R. Nascimento +2
We study gravitational lensing by generalized black-bounce space-times both in regimes of weak and strong field approximations. These metrics interpolate between regular blac…
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…
Geometrical deformation of brane matter field within gravity
Fernando M. Belchior, Roberto V. Maluf, Albert Yu. Petrov +1
In the context of braneworld scenarios, the real scalar field plays a crucial role by providing thickness for brane. In this work, we investigate a codimension-one thick brane with…
