“…We use here the most advanced quasi-circular version of the TEOBResumS model [30,42], that also includes several subdominant modes completed through merger and ringdown. More precisely, we use here the Matlab private implementation of the model (and not the public one written in C [42]) that relies on the iterative determination of the next-to-quasi-circular correction parameters and not on the fits described in Ref. [42].…”

“…[40,41] for the precessing case). The model has been tested [30,42] against NR simulations available up to q = 18. Although the model generates waveforms that look qualitatively sane and robust also for larger mass ratios, only a direct comparison with NR data can effectively probe its performance in the large-q regime.…”

“…The generalization of the quasicircular EOB model TEOBResumS [28,29] to nonquasicircular configurations [9,10,12] has allowed the construction of the first, and currently only, waveform model for spin-aligned black hole binaries that can accurately deal with both hyperbolic captures [10,12,13,30,31] and eccentric inspirals [9,12,13]. The model of Ref.…”

In this paper we assess the performances of different analytical prescriptions for the effectiveone-body (EOB) radiation reaction along generic planar orbits using exact numerical result in the test-mass limit. We consider three prescriptions put forward in the recent literature: (i) the quasicircular prescription (QC), (ii) the QC with 2 post-Newtonian noncircular corrections (QC2PN), (iii) the QC corrected by the noncircular Newtonian prefactor (NCN). The analytical fluxes are then compared against the exact fluxes that are computed by solving the Teukolsky equation with a testmass source in geodesic motion. We find that the NCN prescription is the most accurate for both eccentric and hyperbolic orbits and it is in robust agreement also for large values of the eccentricity. This result carries over to the comparable masses, as we discuss for a numerical-relativity (NR) case study. We also demonstrate that, while the EOB/NR waveform unfaithfulness is a necessary check for the precision of EOB models, the direct comparison of EOB/NR fluxes is a more stringent and informative test to select the best prescription. Finally, we propose an improved NCN2PN radiation reaction that includes noncircular 2PN corrections, in resummed form, as a further multiplicative contribution and that is valid for any mass ratio.

“…The EOB formalism is a framework that combines information from PN theory, NR and BH perturbation theory to accurately describe the inspiral, merger and ringdown of a binary coalescence (see e.g., Refs. [124,[127][128][129][130][131][132][133][134][135][136][137][138][139]). The current eccentric EOB waveform models are constructed by improving the EOB description of the eccentric inspiral and plunge, but they still employ a quasicircular merger-ringdown model [121][122][123][124].…”

We construct an inspiral-merger-ringdown eccentric gravitational-wave (GW) model for binary black holes with non-precessing spins within the effective-one-body formalism. This waveform model, SEOBNRv4EHM, extends the accurate quasi-circular SEOBNRv4HM model to eccentric binaries by including recently computed eccentric corrections up to 2PN order in the gravitational waveform modes, notably the (l, |m|) = (2, 2), (2, 1), (3, 3), (4, 4), (5, 5) multipoles. The waveform model reproduces the zero eccentricity limit with an accuracy comparable to the underlying quasi-circular model, with the unfaithfulness of 1% against quasicircular numerical-relativity (NR) simulations. When compared against 28 public eccentric NR simulations from the Simulating eXtreme Spacetimes catalog with initial orbital eccentricities up to e 0.3 and dimensionless spin magnitudes up to +0.7, the model provides unfaithfulness < 1%, showing that both the (2, |2|)-modes and the higher-order modes are reliably described without calibration to NR datasets in the eccentric sector. The waveform model SEOBNRv4EHM is able to qualitatively reproduce the phenomenology of dynamical captures, and can be extended to include spin-precession effects. It can be employed for upcoming observing runs with the LIGO-Virgo-KAGRA detectors and used to re-analyze existing GW catalogs to infer the eccentricity parameters for binaries with e 0.3 (at 20 Hz or lower) and spins up to 0.9 − 0.95. The latter is a promising region of the parameter space where some astrophysical formation scenarios of binaries predict mild eccentricity in the ground-based detectors' bandwidth. Assessing the accuracy and robustness of the eccentric waveform model SEOBNRv4EHM for larger eccentricities and spins will require comparisons with, and, likely, calibration to eccentric NR waveforms in a larger region of the parameter space.
