Description
The ringdown of black holes provides a rich arena for exploring complementary perspectives on gravity, from classical general relativity to effective descriptions, numerical simulations, and analog systems. In this overview talk, I will discuss several recent developments in black hole ringdown physics, including the mapping between bound states and quasi-normal modes, progress in parametrized quasi-normal mode frameworks, and semi-analytic approaches to ringdown modeling. I will also review advances in black hole spectroscopy using non-linear simulations, with particular attention to non-vacuum environments and possible systematic effects. Finally, I will discuss how simulation-based inference may offer a powerful route to parameter estimation in analog-gravity quantum simulators of black holes.
