摘要
在康普顿伽马射线天文台时代之后，AGILE和费米卫星推动了伽马射线波段对伽马射线暴(GRB)的观测。AGILE和费米正显示出，GeV明亮的伽马射线暴具有一系列共同特征，特别是从keV到GeV能段的高流量、最小洛伦兹因子的高值、伽马射线延展辐射的存在（通常相对于较低能量有延迟），以及最后可能存在的多谱分量。GRB 100724B由费米和行星际网络联合定位，是迄今为止AGILE在伽马射线波段探测到的最亮暴。GRB 100724B的特征包括MeV和GeV的同时发射（如互相关函数分析所示，没有延迟起始或时间滞后），以及在事件持续时间内硬X射线显著的谱演化。在本文中，我们展示了GRB 100724B的AGILE数据分析，并讨论了其在迄今观测到的伽马射线暴以及近期提出的模型背景下的特征。
