摘要

本文报道了Fermi大面积望远镜(LAT)在100 MeV以上观测到GRB 110625A的γ射线余辉。伽马射线的发射在爆发后180秒到580秒之间被清楚地探测到。GeV光曲线不同于幂律衰变，可能由两个发射周期组成。同时进行的Swift/XRT观测没有显示出耀斑行为，将其与GRB 100728A的扩展GeV发射源区分开来。©EAS, EDP Sciences 2013。(5)参考文献

FERMI/LAT OBSERVATIONS OF GRB 110625A

We report γ-ray afterglow observations of GRB 110625A using Fermi's Large Area Telescope (LAT) above 100 MeV. Gamma-ray emission was clearly detected using data taken between 180 s and 580 s after the burst. The GeV light curve differs from a power-law decay, and probably consists of two emission periods. Simultaneous Swift/XRT observations did not show flaring behaviors, distinguishing its origin of the extended GeV emission from the case of GRB 100728A. © EAS, EDP Sciences 2013.(5 refs)
