摘要:

本文给出了一个计算两个黑洞合并产生的黑洞自旋的简洁解析公式。该表达式使用数值相对论数据的分析拟合并依赖于四个假设,旨在对通用初始自旋配置和质量比进行建模。与数值相对论模拟的比较已经显示出与迄今为止所有可用的数值数据非常准确的一致性,但我们也提出了一些可以进一步改进我们的预测的方法。

英文摘要:

We provide a compact analytic formula to compute the spin of the black hole produced by the coalescence of two black holes. The expression, which uses an analytic fit of numerical-relativity data and relies on four assumptions, aims at modelling generic initial spin configurations and mass ratios. A comparison with numerical-relativity simulations already shows very accurate agreements with all of the numerical data available to date, but we also suggest a number of ways in which our predictions can be further improved.
