Adiabatic waveforms for extreme mass-ratio inspirals via multivoice decomposition in time and frequency

no code implementations4 Feb 2021 Scott A. Hughes, Niels Warburton, Gaurav Khanna, Alvin J. K. Chua, Michael L. Katz

We compute adiabatic waveforms for extreme mass-ratio inspirals (EMRIs) by "stitching" together a long inspiral waveform from a sequence of waveform snapshots, each of which corresponds to a particular geodesic orbit.

Exciting black hole modes via misaligned coalescences: II. The mode content of late-time coalescence waveforms

no code implementations17 Jan 2019 Halston Lim, Gaurav Khanna, Anuj Apte, Scott A. Hughes

In this paper, we examine how the modes' excitations vary as a function of source parameters, such as the larger black hole's spin and the geometry of the smaller body's inspiral and plunge.

Learning about black hole binaries from their ringdown spectra

no code implementations17 Jan 2019 Scott A. Hughes, Anuj Apte, Gaurav Khanna, Halston Lim

Measuring the frequency and decay time of multiple modes makes it possible to measure the remnant's mass and spin, and to test the waves against the predictions of gravity theories.

Small mass plunging into a Kerr black hole: Anatomy of the inspiral-merger-ringdown waveforms

no code implementations7 Apr 2014 Andrea Taracchini, Alessandra Buonanno, Gaurav Khanna, Scott A. Hughes

We study the large-spin regime, and find a great simplicity in the merger waveforms, thanks to the extremely circular character of the plunging orbits.
