Scalar absorption cross section of rotating black holes with tidal charge

E. S. de Oliveira

The absorption cross section of rotating black holes in the Randall-Sundrum brane-world scenario for massless scalar waves is obtained via the partial-wave method. A variety of inc…

Scalar scattering from charged black holes on the brane

Ednilton S. de Oliveira

The differential scattering cross section of the massless scalar field localized on the 3-brane of charged static black holes in the ADD model is analyzed. While results valid in t…

Scattering of massless scalar waves from Schwarzschild-Tangherlini black holes on the brane

Cássio I. S. Marinho, Ednilton S. de Oliveira

The scalar scattering cross section is computed for Schwarzschild-Tangherlini black holes on the brane. The cross sections are computed numerically via the partial-wave method. The…

Scalar waves in regular Bardeen black holes: Scattering, absorption and quasinormal modes

Caio F. B. Macedo, Luís C. B. Crispino, Ednilton S. de Oliveira

We discuss the phenomenology of massless scalar fields around a regular Bardeen black hole, namely absorption cross section, scattering cross section and quasinormal modes. We comp…

Scattering from charged black holes and supergravity

Luís C. B. Crispino, Sam R. Dolan, Atsushi Higuchi +1

The scattering cross sections of the unpolarized electromagnetic and gravitational waves are shown to be equal for the extreme Reissner-Nordström black hole using supergravit…

Scattering by regular black holes: Planar massless scalar waves impinging upon a Bardeen black hole

Caio F. B. Macedo, Ednilton S. de Oliveira, Luís C. B. Crispino

Singularities are common features of general relativity black holes. However, within general relativity, one can construct black holes that present no singularities. These regular…

Greybody factors for rotating black holes in higher dimensions

Rogério Jorge, Ednilton S. de Oliveira, Jorge V. Rocha

We perform a thorough study of greybody factors for minimally-coupled scalar fields propagating on the background of rotating black holes in higher (odd) dimensions with all angula…

Inferring black hole charge from backscattered electromagnetic radiation

Luís C. B. Crispino, Sam R. Dolan, Atsushi Higuchi +1

We compute the scattering cross section of Reissner-Nordström black holes for the case of an incident electromagnetic wave. We describe how scattering is affected by both the conve…

Absorption of a massive scalar field by a charged black hole

Carolina L. Benone, Ednilton S. de Oliveira, Sam R. Dolan +1

We calculate the absorption cross section of a massive neutral scalar field impinging upon a Reissner-Nordström black hole. First, we derive key approximations in the high- and low…
