论文摘要
根据GW150914的数据，最近的重力波观察证实了Hawking的区域定理，并估计了两个Kerr黑洞的合并过程中总平线总面积的增加。我们使用此结果和第二定律的有效性来获得4D拓扑高斯 - 巴内特耦合的第一个观测，为$γ\ sillsim 2.804^{+7.946} _ { - 1.169} \ times 10^{9}} {9} \，m^，m^2 $ with $ 95 $ $ 95 \％$ 95 \％$ $ $ $ $ $ $。
Recent gravitational wave observation based on the data from GW150914 has confirmed Hawking's area theorem and estimated the increase in total horizon area during a merger process of two Kerr black holes. We use this result and the validity of the second law to obtain the first observational bound on the 4D topological Gauss-Bonnet coupling as $γ\lesssim 2.804^{+7.946}_{-1.169} \times 10^{9}\, m^2$ with $95 \%$ credibility.
