Absorption of scalar waves by static black holes and analogues
(2012-01-01)
We compute numerically the scalar absorption cross section for Reissner-Nordstrom black holes and the absorption cross section of canonical acoustic holes. Copyright © 2012 by World Scientific Publishing Co. Pte. Ltd.
Absorption cross section of canonical acoustic holes
(Amer Physical Soc, 2007-11-01)
We compute numerically the absorption cross section of a canonical acoustic hole for sound waves with arbitrary frequencies. Our outputs are in full agreement with the expected low- and high-frequency limits.

A qualitative spatial representation of string loops as holes
(2016)
© 2016 Published by Elsevier B.V.This research note contains an extension of a previous work by Cabalar and Santos (2011) that formalised several spatial puzzles formed by strings and holes. That approach explicitly ignored ...
Scattering of sound waves by a canonical acoustic hole
(AMER PHYSICAL SOC, 2009)
This is a study of a monochromatic planar perturbation impinging upon a canonical acoustic hole. We show that acoustic hole scattering shares key features with black hole scattering. The interference of wave fronts passing ...
