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 γ2.8041.169+7.946×109m2 with 95% credibility.

从 GW150914 约束拓扑 Gauss-Bonnet 耦合

最近基于 GW150914 数据的引力波观测证实了霍金面积定理,并估计了两个克尔黑洞合并过程中总视界面积的增加。我们使用这个结果和第二定律的有效性来获得 4D 拓扑 Gauss-Bonnet 耦合的第一个观测界为γ2.804-1.169+7.946×109295%的可信度。
