论文摘要
Kerr黑洞的质量可以分离成不可约和旋转成分 - 前者是无法从事件范围中提取的能量的下限，并且与其面积有关。在这里，我们计算引力波干涉仪Ligo和处女座观察到的恒星质量黑孔的不可还原质量。使用单个事件数据，我们提出了后验分布的重新分配，该分布明确强调了对总能量的不可还原和旋转贡献。我们利用该区域法来对迄今为止观察到的黑洞合并对其不可逆性进行排名，从而为选择有针对性的一般相对性测试的事件提供了指南。使用种群拟合，我们计算了由于可观察到的合并而导致黑洞范围总面积增加的速率。
The mass of a Kerr black hole can be separated into irreducible and rotational components -the former is a lower limit to the energy that cannot be possibly extracted from the event horizon and is related to its area. Here we compute the irreducible masses of the stellar-mass black holes observed by gravitational-wave interferometers LIGO and Virgo. Using single-event data, we present a re-parametrization of the posterior distribution that explicitly highlights the irreducible and rotational contributions to the total energy. We exploit the area law to rank the black-hole mergers observed to date according to their irreversibility, thus providing a guide to selecting events for targeted tests of General Relativity. Using population fits, we compute the rate by which the total area of black-hole horizons increases due to the observable mergers.
