Fast emri waveforms
WebAug 10, 2024 · This version of the AAK model has improved accuracy compared to its predecessors, with two-month waveform overlaps against a more accurate fiducial model exceeding 0.97 for a generic range of sources; it also generates waveforms 5-15 times faster than the fiducial model. WebTo assess this we use two different waveform models: the Analytical Kludge [13] and the Augmented Analytical Kludge as implemented in the Fast EMRI waveform package [28][29] [30] [31][32][33]. We ...

Webtional resource [34{36]. To generate fast waveforms, most parameter estimations on EMRI sources adopt the so-called \kludge" models [37{39]. The \analytic kludge" (AK) model is the rst kludge waveform pro-posed by Barack and Cutler. In the AK model, the CO is moving on a quasi-Keplerian ellipse with the or-bital parameters slowly evolving under ... WebContrasting with the slow gravitational self-force waveform models are the fast EMRI “kludge” models which are designed to be rapidly evaluated for use in LISA data analysis studies [30, 31, 32, 33].These models capture the phenomenology of generic EMRI waveforms but only have an approximation to the correct phasing and amplitudes.
