Scalar scattering from black holes with tidal charge
Ednilton S. de Oliveira
The cross sections of black holes with tidal charge predicted in the context of the Randall--Sundrum brane-world scenario are computed considering the massless scalar field. Result…
Addendum to "Absorption of a massive scalar field by a charged black hole"
Carolina L. Benone, Ednilton S. de Oliveira, Sam R. Dolan +1
In Phys.Rev.D89, 104053 (2014) we studied the absorption cross section of a scalar field of mass impinging on a static black hole of mass and charge . We presented numer…
Tidal Forces in Reissner-Nordström Spacetimes
Luís C. B. Crispino, Atsushi Higuchi, Leandro A. Oliveira +1
We analyze the tidal forces produced in the spacetime of Reissner-Nordström black holes. We point out that the radial component of the tidal force changes sign just outside the eve…
Absorption of planar massless scalar waves by Kerr black holes
Caio F. B. Macedo, Luiz C. S. Leite, Ednilton S. Oliveira +2
We consider planar massless scalar waves impinging upon a Kerr black hole, for general angles of incidence. We compute the absorption cross section via the partial wave approach, a…
Greybody factors for non-minimally coupled scalar fields in Schwarzschild-de Sitter spacetime
Luís C. B. Crispino, Atsushi Higuchi, Ednilton S. Oliveira +1
We compute the greybody factors for non-minimally coupled scalar fields in four-dimensional Schwarzschild-de Sitter spacetime. In particular, we demonstrate that the zero-angular-m…
Scattering by a draining bathtub vortex
Sam R. Dolan, Ednilton S. Oliveira
We present an analysis of scattering by a fluid-mechanical `black hole analogue', known as the draining bathtub vortex: a two-dimensional flow which possesses both a sonic horizon…
