The Fourth RIT binary black hole simulations catalog: Extension to Eccentric Orbits

TL;DR

This paper introduces an extensive catalog of 1881 numerical relativity black-hole-binary waveforms, including eccentric orbits, and analyzes correlations among their properties for astrophysical applications.

Contribution

It extends the RIT waveform catalog to include eccentric orbits and provides detailed initial parameters, waveform corrections, and analysis of correlations among remnant properties.

Findings

New correlations among peak radiation and remnant properties are identified.

The catalog includes waveforms for a wide range of mass ratios, spins, and eccentricities.

Waveforms are corrected for center of mass drift and extrapolated to null infinity.

Abstract

This fourth release of the RIT public catalog of numerical relativity black-hole-binary waveforms \url{http://ccrg.rit.edu/~RITCatalog} consists of 1881 accurate simulations that include 446 precessing and 611 nonprecessing quasicircular/inspiraling binary systems with mass ratios $q=m_1/m_2$ in the range $1/128\leq q\leq1$ and individual spins up to $s/m^2=0.95$; and 824 in eccentric orbits in the range $0<e\leq1$. The catalog also provides initial parameters of the binary, trajectory information, peak radiation, and final remnant black hole properties. The waveforms are corrected for the center of mass drifting and are extrapolated to future null infinity. As an application of this waveform catalog we reanalyze all of the peak radiation and remnant properties to find new, simple, correlations among them, valid in the presence of eccentricity, for practical astrophysical usage.
