Dissection of a merger-ringdown waveform in the small-mass-ratio limit
Patrick Bourg, Lorenzo Küchler, Benjamin Leather +6
Work over the past two decades has unveiled the rich phenomenology of black hole binary mergers and subsequent ringdowns, involving a tapestry of quasinormal modes (QNMs), nonlinea…

Self-force framework for transition-to-plunge waveforms
Lorenzo Küchler, Geoffrey Compère, Leanne Durkan +1
Compact binaries with asymmetric mass ratios are key expected sources for next-generation gravitational wave detectors. Gravitational self-force theory has been successful in produ…

Black Hole Photon Rings Beyond General Relativity
Seppe Staelens, Daniel R. Mayerson, Fabio Bacchini +2
We investigate whether photon ring observations in black hole imaging are able to distinguish between the Kerr black hole in general relativity and alternative black holes that dev…
