AI总结:

通过分析GW230814数据,验证了黑洞面积定律,证实合并后黑洞视界面积大于合并前总视界面积,支持广义相对论在强场区域的正确性。

摘要:

我们利用刚发布的GWTC-4.0引力波数据,对霍金的黑洞面积定理进行了观测确认。我们分析了高信噪比的双黑洞合并信号GW230814,并测量了合并前后的黑洞总视界面积。对于优选(且合理的)后截断起始时间选择,残余黑洞的视界面积在高可能性(至少大于等于99.5%)下大于两个预合并黑洞的总视界面积。重要的是,我们的分析考虑了天空位置不确定性。这些结果提供了对黑洞面积定律的严格观测确认,进一步巩固了经典广义相对论在动态强场区域的有效性。

英文摘要:

We present an observational confirmation of Hawking's black-hole area theorem using the newly released gravitational-wave data from the GWTC-4.0. We analyze the high signal-to-noise ratio binary black hole (BBH) merger GW230814 and measure the (total) horizon area of the black holes before and after the merger. For preferred (and reasonable) choices of the post-truncation start time, the horizon area of the remnant black hole is found to be greater than the total horizon area of the two pre-merger black holes at a high possibility (at least $\gtrsim 99.5\%$). Importantly, our analysis accounts for sky-location uncertainty. These results provide a stringent observational confirmation of the black-hole area law, further bolstering the validity of classical general relativity in the dynamical, strong-field regime.
