Scattering and absorption by extra-dimensional black holes with GUP
M. A. Anacleto, J. A. V. Campos, F. A. Brito +2
In this paper, we consider the Schwarzschild-Tangherlini black hole to investigate the process of scalar wave scattering by the black hole in a spacetime of (d + 1) dimensions and…

Absorption, scattering, quasinormal modes and shadow by canonical acoustic black holes in Lorentz-violating background
J. A. V. Campos, M. A. Anacleto, F. A. Brito +1
In the present work, we study the scattering for a black hole described by the canonical acoustic metric with Lorentz violation using asymptotic and numerical methods. In this scen…
