The gamma-ray burst GRB 221009A is among the most luminous of its kind and its proximity to Earth has made it an exceptionally rare observational event. The International Gamma-ray Astrophysics Laboratory (INTEGRAL) was in an optimal aspect position to use its all-sky instruments for recording the prompt emission and early gamma-ray afterglow in unprecedented detail. Following the initial detection, a swiftly scheduled follow-up observation allowed for the hard X-ray afterglow time and spectral evolution to be observed for up to almost a week. The INTEGRAL hard X-ray and soft gamma-ray observations have started to bridge the energy gap between the traditionally well-studied soft X-ray afterglow and the high-energy afterglow observed by Fermi/LAT. We discuss the possible implications of these observations for follow-ups of multi-messenger transients with hard X-ray and gamma-ray telescopes.

GRB 221009A 的整体视图
伽马射线爆发 GRB 221009A 是同类中最明亮的之一，它距离地球很近，使其成为极其罕见的观测事件。国际伽马射线天体物理实验室（INTEGRAL）处于最佳位置，可以使用其全天空仪器以前所未有的细节记录瞬时发射和早期伽马射线余辉。初次探测后，迅速安排的后续观察允许观察硬 X 射线余辉时间和光谱演变长达近一周。 INTEGRAL硬X射线和软伽马射线观测已经开始弥合传统上充分研究的软X射线余辉和费米/LAT观测到的高能余辉之间的能隙。我们讨论了这些观测结果对于用硬 X 射线和伽马射线望远镜跟踪多信使瞬变的可能影响。
