本项目拟基于Insight-HXMT、Swift 和 Fermi三颗在轨天文卫星及地面探测设备联合观测数据的基础上，对伽玛射线暴瞬时辐射的光变曲线和能谱特性等观测数据进行处理和分析，然后再对伽玛射线暴中心引擎和喷流成分等相关问题，进行探讨和研究。具体研究内容如下：1、利用Insight-HXMT卫星探测的平滑的单脉冲暴及其它联合观测结果，研究伽玛暴的辐射机制，限定洛伦兹因子及前身星演化等；2、对伽玛射线暴瞬时阶段多脉冲光变的统计和分析；3、研究伽玛射线暴瞬时阶段多成分能谱的叠加和演化；4、Insight-HXMT短伽玛射线暴与引力波的探测率。

We plan to study the prompt light curves and energy spectra from gamma-ray bursts (GRBs) which were observed by Insight-HXMT, Swift, Fermi satellites and some ground-based telescopes. Some important issues about GRBs, i.e., the type of central engine and progenitor of GRBs are needed to be further discussed. The detail studies about this project are presented as follows: (1). constraint the initial Lorentz factor and ambient medium of GRBs with the single long and smooth γ-ray emission pulse; (2). statistics and analysis of the multipulse structures appearing in GRB light curves (3). investigate the evolution of the various components for the prompt emission spectra; (4). the expected rate of joint gravitational-wave (GW) and short GRB of Insight-HXMT.
