论文摘要
需要多种方法来研究黑洞二进制的演变。虽然牛顿后近似足以描述早期的灵感（即使是从无限大的轨道分离中），但只有数值相对性才能捕获合并附近动力学的全部复杂性。我们将多次纳维顿后整合的多时间结合使用数值替代性替代模型，从而将二进制的整个历史记录从上届无穷大的渐近配置映射到合并后的残留物。这种方法自然地使我们能够评估遵从残余物的质量，自旋和踢的进化阶段和轨道相位的影响。在连接二元进化的两个极端时，这些阶段会引入基本的不确定性。
Multiple approaches are required to study the evolution of black-hole binaries. While the post-Newtonian approximation is sufficient to describe the early inspiral (even from infinitely large orbital separation), only numerical relativity can capture the full complexity of the dynamics near merger. We combine multi-timescale post-Newtonian integrations with numerical-relativity surrogate models, thus mapping the entire history of the binary from its asymptotic configuration at past-time infinity to the post-merger remnant. This approach naturally allows us to assess the impact of the precessional and orbital phase on the properties - mass, spin, and kick - of the merger remnant. These phases introduce a fundamental uncertainty when connecting the two extrema of the binary evolution.
