High Precision Ringdown Modeling: Multimode Fits and BMS Frames

ORAL

Abstract

Quasi-normal mode (QNM) modeling is an invaluable tool for studying strong gravity, characterizing remnant black holes, and testing general relativity. To date, most studies have focused on the dominant $(2,2)$ mode. But, as gravitational wave observatories become more sensitive, they can resolve higher-order modes. Multimode fits will be critically important, and in turn require a more thorough treatment of the asymptotic frame at null infinity. We present a technique to systematically fit a QNM model containing many modes, and also illustrate the importance of mapping the numerical waveforms to the correct Bondi-Metzner-Sachs frame of numerical simulations to obtain high accuracy.
