摘要
GRB 221009A 被称为有史以来最亮（the Brightest Of All Time，BOAT）。我们通过将其与半个世纪的伽马射线暴瞬时观测进行比较，来考察这一说法的真实性。该暴在峰值流量与总辐射量度量上均为迄今探测到的最亮。出乎意料的是，GRB 221009A 具有已确认的最高各向同性等效总能量，而其峰值光度位于已知分布的约第 百分位。我们探讨了此类暴的供能机制，并讨论其对超长与高红移伽马射线暴的潜在启示。通过总辐射量与峰值流量分布的几何外推，GRB 221009A 似乎是万年一遇的事件。因此，尽管它几乎肯定不是整个宇宙历史中的 BOAT，它可能是自人类文明开始以来最亮的伽马射线暴。
