Rotating black holes in a draining bathtub: superradiant scattering of gravity waves
(2015)
Journal Article
In a draining rotating fluid flow background, surface perturbations behave as a scalar field on a rotating effective black hole spacetime. We propose a new model for the background flow which takes into account the varying depth of the water. Numeric...
