除了惊人的质量外，这两个黑洞还展现出了极其罕见的自旋特征。 分析显示，它们都在以接近广义相对论理论允许的极限速度旋转，自旋参数分别达到 0.9 和 0.8，而理论最大值为 1。 这种极高的自旋速度为理解其形成机制提供了关键线索。当两个黑洞合并时，合并产生的黑洞通常会获得更快的自转速度， 因此 GW231123 中涉及的黑洞很可能是早期较小黑洞合并事件的产物， ...

这次合并涉及的两个黑洞质量分别约为 103 倍和 137 倍太阳质量，远超过此前的纪录保持者。2021年探测到的 GW190521 事件曾创下当时的最高纪录，合并后产生的黑洞质量约为 140 倍太阳质量，而 GW231123 的结果比这一数字高出了 ...
