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

摘要： 本第四版RIT公开的数值相对论双黑洞波形目录\url{http://ccrg.rit.edu/~RITCatalog}包括1881个精确模拟，其中包括446个进动和611个非进动的准圆/旋近双星系统，质量比$q=m_1/m_2$范围在$1/128\leq q\leq1$之间，单个自旋高达$s/m^2=0.95$；以及824个处于偏心轨道的系统，范围在$0<e\leq1$之间。 该目录还提供了双星的初始参数、轨迹信息、峰值辐射和最终残余黑洞属性。 波形已校正质心漂移，并被外推到未来的类空无穷远。 作为该波形目录的应用，我们重新分析了所有峰值辐射和残余属性，以发现它们之间新的、简单的相关性，在存在偏心率的情况下适用于实际天体物理用途。 显示英文摘要

摘要： 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.
