宇宙高能辐射研究

伽马暴和引力波电磁对应体的研究是最近研究的热门课题。本项目将利用慧眼-HXMT的连续性观测数据研究伽马暴的时变和能谱性质，结合已有的观测结果研究能谱时延和最小光变时标。根据能谱时延和最小光变时标，以及能谱性质，对伽马暴的各种模型进行检验。实时监测引力波电磁对应体和快速射电暴伽马辐射，并进行必要的后随观测。争取观测到引力波电磁对应体或者是给出相应能段的流强限制。

Gamma-ray bursts (GRBs) and the electromagnetic counterparts of gravitational waves have become hot topics for astrophysical researches. Based on the observational data of insight-HXMT, this project aims to study the temporal and spectral properties of GRBs, especially on the spectral lags and the minimum variability timescale. With the analyzed results, the properties of central engine and the prompt emission mechanisms can be constrained. Besides, insight-HXMT will be used to monitor the high-energy electromagnetic counterparts of merger events and fast radio bursts. Follow-up observations will be carried out if necessary.
