A Rosetta Stone for Eccentric Gravitational Waveform Models

Abstract: Orbital eccentricity is a key signature of dynamical binary black hole formation. The gravitational waves from a coalescing binary contain information about its orbital eccentricity, which may be measured if the binary retains sufficient eccentricity near merger. Dedicated waveforms are required to measure eccentricity. Several models have been put forward, and show good agreement with numerical relativity at the level of a few percent or better. However, there are multiple ways to define eccentricity for insp… Show more

“…This means that an eccentricity inferred with SEOBNRE does not exactly equate to the eccentricity that would be inferred with another model, and that comparisons to predictions made by simulations of dynamical environments should be taken as indicative rather than absolute. Work is ongoing to establish a translation guide between the eccentricities defined by various simulations (Knee et al 2022). 7.…”

“…However, if the parameters preferred by the quasi-circular model are totally removed from the true quasi-circular parameters, then the eccentricity posterior obtained through the reweighting method is unlikely to both recover a high eccentricity and be well sampled; therefore, we use 3.9% as our expected eccentric fraction. The predictions in Zevin et al (2021a) were obtained using a different eccentric waveform model, TEOBResumS (Nagar et al 2018); for an overview of key differences between TEOBResumS and SEOBNRE, see Knee et al (2022). Since the overlap between SEOBNRE and TEOBResumS is 90% >  in LVK noise over the eccentricity range studied here (Knee et al 2022), we assume in this paper that the results of Zevin et al (2021a) are robust to waveform choice.…”

“…This led to the development of, on the one hand, numerical relativity simulations aimed at obtaining waveform templates [480], and, on the other hand, approximate methods, or approximants, that greatly reduced the computational cost of data analysis but generally they are generally constructed on the leading order of GW signal expansion [479, e.g.]. A recently developed technique, however, enabled the possibility to retrieve information on the binary eccentricity at a small computational cost [481,482], and permitted to place constrains on the eccentricity of LVC sources, suggesting that up to 4 of them might be eccentric sources [146,148]. In the frequency range of LVC detectors, i.e.…”

“…Placing constraints on the eccentricity of observed mergers became possible only in recently [e.g. [143][144][145][146], and led to place constraints on the eccentricity of up to 4 LVC sources, for which possibly e > 0.1 [147][148][149][150]. Interestingly, for eccentric sources the accuracy on the parameter measurement can significantly increase, e.g.,the chirp mass(localization) accuracy of an eccentric 30 − 30M BBH can be ∼ 10 1 (10 2 ) times higher than for the circular case [151].…”
