Effective one-body multipolar waveform model for spin-aligned, quasicircular, eccentric, hyperbolic black hole binaries

Building upon recent work, we present an improved effective-one-body (EOB) model for spin-aligned, coalescing, black hole binaries with generic orbital configurations, i.e. quasi-circular, eccentric or hyperbolic orbits. The relies on the idea of incorporating general Newtonian prefactors, instead usual quasi-circular ones, in both radiation reaction and waveform. major advance respect to previous work is that limit now correctly informed by numerical relativity (NR) simulation. This provides EOB/NR unfaithfulness dominant quadrupolar waveform, calculated Advanced LIGO noise, at most order $1\%$ over a meaningful portion NR simulations Simulating eXtreme Spacetime (SXS) collaboration. In presence eccentricity, similarly NR-faithful, $\lesssim 1\%$, all 28 public SXS datasets, initial eccentricity up $\simeq 0.2$ , mass ratio $q=3$ dimensionless spin magnitudes as large $+0.7$. Higher multipoles, $\ell=5$ are also reliably modeled through inspiral, plunge merger ringdown. For hyperbolic-like show EOB computed scattering angle excellent agreement currently available results.
