摘要
GRB221009A 是迄今为止探测到的最亮的伽马射线暴。为了探测甚高能 (VHE, \!100 GeV) 辐射，高能立体视野望远镜系统 (H.E.S.S.) 在触发事件发生 53 小时后开始观测，此时月光亮度不再阻碍观测。在应用大气修正后，我们利用初始伽马射线暴探测后第三、第四和第九个夜晚的 H.E.S.S. 数据推导了微分和积分通量上限。综合观测得到的积分能通量上限为 （在 GeV 以上）。从 H.E.S.S. 观测得出的约束补充了现有的多波长数据。从射电到 X 射线波段的数据与单一电子群产生的同步辐射一致，SED 的峰值出现在 X 射线波段以上。与 VHE 明亮的 GRB190829A 相比，GRB221009A 的上限意味着余辉中的伽马射线与 X 射线通量之比更小。即使在未探测到信号的情况下，H.E.S.S. 的上限依然为 GRB221009A 的多波长图景做出了贡献，有效地排除了由 IC 主导的场景。
