When is a sloshing vortex an analogue black hole bomb?
Sam Patrick, Leonardo Solidoro, Maurício Richartz +4
Draining vortices provide a powerful platform for simulating black hole phenomena in tabletop experiments. In realistic fluid systems confined within a finite container, low-freque…
Ergodic Hysteresis of the Kerr black hole spectrum
João Paulo Cavalcante, Maurício Richartz, Bruno Carneiro da Cunha
We uncover a cascade of exceptional points (EPs) in the quasinormal mode spectrum of massive scalar perturbations of Kerr black holes, revealing an intricate non-Hermitian structur…
Pseudospectrum of rotating analog black holes
Lucas Tobias de Paula, Pedro Henrique Croti Siqueira, Rodrigo Panosso Macedo +1
Analyzing the stability of quasinormal modes (QNM) is essential for understanding black hole dynamics, particularly in the context of gravitational wave emissions and black hole sp…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Black-hole spectroscopy from a giant quantum vortex
Pietro Smaniotto, Leonardo Solidoro, Patrik Švančara +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…
Probing the Unstable Spectrum of Schwarzschild-like Black Holes
Pedro Henrique Croti Siqueira, Lucas Tobias de Paula, Rodrigo Panosso Macedo +1
We investigate the pseudospectrum of a Schwarzschild-like spacetime within the framework of black hole perturbation theory to analyze a counterintuitive assertion regarding the ins…
