Rotating black holes in a draining bathtub: superradiant scattering of gravity waves
Mauricio Richartz, Angus Prain, Stefano Liberati +1
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…
The charged McVittie spacetime
Valerio Faraoni, Andres F. Zambrano Moreno, Angus Prain
The two-parameter charged McVittie solution of the Einstein equations is revisited and its apparent horizons are discussed and located numerically (for the extremal case, analytica…
Are there really `black holes' in the Atlantic Ocean?
Angus Prain, Valerio Faraoni
In this letter we point out some interpretational difficulties associated with concepts from General Relativity in a recent article which appeared in J. Fluid Mech. 731 (2013) R4 w…
