费米伽玛射线太空望远镜为伽玛射线暴(GRB)研究开辟了新的高能窗口。在这里,我们提出了一个全面的分析伽玛暴080825 C,它触发了费米伽玛射线暴监测器(GBM),是第一个由费米大面积望远镜(LAT)的伽玛暴的坚定检测。我们讨论了LAT事件的选择,背景估计,显着性计算,并在一般和GRB 080825 C特别费米伽玛暴的本地化。我们展示了GBM和LAT数据的时间和时间分辨谱分析的结果。我们还提出了一些理论解释的GRB 080825 C的观测以及在其他LAT GRB中观察到的一些共同特征。
The Fermi Gamma-ray Space Telescope has opened a new high-energy window in the study of gamma-ray bursts (GRBs). Here we present a thorough analysis of GRB 080825C, which triggered the Fermi Gamma-ray Burst Monitor (GBM), and was the first firm detection of a GRB by the Fermi Large Area Telescope (LAT). We discuss the LAT event selections, background estimation, significance calculations, and localization for Fermi GRBs in general and GRB 080825C in particular. We show the results of temporal and time-resolved spectral analysis of the GBM and LAT data. We also present some theoretical interpretation of GRB 080825C observations as well as some common features observed in other LAT GRBs.
