Black-hole spectroscopy from a giant quantum vortex
Pietro Smaniotto, Leonardo Solidoro, Patrik Å vanÄara +5
Black-hole spectroscopy aims to infer the fundamental properties of black holes by analysing the spectrum of gravitational waves emitted as they settle into equilibrium. These reso…

On the origin of quasinormal modes in semi-open systems
Leonardo Solidoro, Sam Patrick, Ruth Gregory +1
Astrophysical black holes are open systems which, when perturbed, radiate quasi-normal modes (QNMs) to infinity. By contrast, laboratory analogues are necessarily finite-sized, pre…
