Quasinormal modes and Regge poles of the canonical acoustic hole
Sam R. Dolan, Leandro A. Oliveira, Luis C. B. Crispino
We compute the quasinormal mode frequencies and Regge poles of the canonical acoustic hole (a black hole analogue), using three methods. First, we show how damped oscillations aris…

Ergoregion instability: The hydrodynamic vortex
Leandro A. Oliveira, Vitor Cardoso, Luís C. B. Crispino
Four-dimensional, asymptotically flat spacetimes with an ergoregion but no horizon have been shown to be linearly unstable against a superradiant-triggered mechanism. This result h…
