论文摘要
Hawking的区域定理是黑洞（BHS）的基本定律之一，该定律已独立地分析GW信号的Inspiral and Ringdown部分，以$ \ sim 95 \％$的置信度（GW）观察进行了测试。在这项工作中，我们建议通过分层三重合并以新的方式进行测试（即，连续的两次BH合并在GW探测器的观察窗口内依次发生），祖先BHS的属性和第一个合并的遗物BH的性质可以从两个Mers of Dimper of Mern Mergggers ers portions of Dimper portions中落下。正如我们在模拟中揭示的那样，可以在Ligo/gagra/kagra/Ligo-India的O4/O5运行中检测到的一些合理的层次三重合并事件，可以很好地确认BH地区法律。我们提出的方法为测试区域法律提供了重要的促进，并补充了以前的方法。
Hawking's area theorem is one of the fundamental laws of black holes (BHs), which has been tested at a confidence level of $\sim 95\%$ with gravitational wave (GW) observations by analysing the inspiral and ringdown portions of GW signals, independently. In this work, we propose to carry out the test in a new way with the hierarchical triple merger (i.e., two successive BH mergers occurred sequentially within the observation window of GW detectors), for which the properties of the progenitor BHs and the remnant BH of the first coalescence can be inferred from the inspiral portions of the two mergers. As revealed in our simulations, the BH area law can be well confirmed for some plausible hierarchical triple merger events detectable in LIGO/Virgo/KAGRA/LIGO-India's O4/O5 runs. Our proposed method provides significant facilitation for testing the area law and complements previous methods.
