论文摘要
黑洞热力学给重力，热力学和量子理论之间的深刻和基本联系带来了强烈的暗示。如果黑洞的表现像天然热力学系统，则应在干净的环境中进行热力学稳定。在本文中，使用Ligo，处女座和Kagra探测器观察到的二进制黑洞（BBH）合并的观察数据，我们检查了Ligo-Virgo-Kagra-Kagra Catalog Catalog GWTC-3中BBH合并产生的黑洞残留物是否是热稳定的。热力学稳定性的标准非常简单，与黑洞的旋转直接相关，该旋转指出，热力学稳定的黑洞残留物需要其无量纲的旋转$ A> a_* \ simeq 0.68 $。我们检查了GWTC-3中83个黑洞残留物的最终旋转$ A_F $的后验分布，发现整个残留人群与热力学上稳定的黑洞一致，$ 99.98 \％$ $概率。这是对BBH合并产生的黑洞残留物的热力学稳定性的首次验证。
Black hole thermodynamics has brought strong hints of a profound and fundamental connection between gravity, thermodynamics, and quantum theory. If the black hole does behave like a natural thermodynamic system, it should be thermodynamically stable in a clean environment. In this paper, using the observational data of binary black hole (BBH) mergers observed by LIGO, Virgo, and KAGRA detectors, we check whether the black hole remnants produced from BBH mergers in the LIGO-Virgo-KAGRA catalog GWTC-3 are thermodynamically stable. The criterion for the thermodynamic stability is quite simple and is directly related to the black hole's spin, which states that a thermodynamically stable black hole remnant requires its dimensionless spin $a>a_* \simeq 0.68$. We check the posterior distributions of final spin $a_f$ for 83 black hole remnants in GWTC-3 and find the whole remnant population is consistent with the thermodynamically stable black hole with $99.98\%$ probability. This is the first verification of the thermodynamic stability of black hole remnants produced from BBH mergers.
