Title: "The Astrophysical Promise of Black Hole Ringdowns"

Abstract: "The remnant of a binary black hole coalescence is a perturbed black hole, which equilibrates by emitting ringdown gravitational waves. These ringdown waves not only encode information in their frequencies about the spacetime structure of the remnant black hole metric, but also have imprints in their amplitudes of the pre-merger binary's properties. In this talk I will highlight recent results in black hole ringdown data analysis, and then will discuss how ringdown analyses may become a vital tool for making inferences of binary black hole properties - even in situations where the gravitational wave signal from the binary inspiral itself is never directly observed."
