Absorption and (unbounded) superradiance in a static regular black hole spacetime
Marco A. A. de Paula, Luiz C. S. Leite, Sam R. Dolan +1
Regular black holes (RBHs) -- geometries free from curvature singularities -- arise naturally in theories of non linear electrodynamics. Here we study the absorption, and superradi…
Parametrized black holes: Scattering investigation
Renan B. Magalhães, Luiz C. S. Leite, Luís C. B. Crispino
We study the scattering of light-like geodesics and massless scalar waves by a static Konoplya-Zhidenko black hole, considering the case that the parametrized black hole solution c…
Scattering properties of charged black holes in nonlinear and Maxwell's electrodynamics
Marco A. A. de Paula, Luiz C. S. Leite, Luís C. B. Crispino
We investigate the scattering properties of a massless scalar field in the background of a charged Ayón-Beato-García regular black hole solution. Using a numerical approach, we com…
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…
