摘要:

太阳塔大气切伦科夫效应实验(英语:Solar Tower Atmospheric Cherenkov Effect Experiment,STACEE)是一个大气切伦科夫望远镜(英语:Cherenkov telescope,ACT),它使用大型反射镜阵列来实现相对较低的能量阈值。对于具有类克拉布光谱的源,在高海拔处,探测器响应峰值接近100 GeV。自实验开始以来,伽马射线暴观测一直是STACEE合作的高度优先事项。我们提出的结果,20伽玛射线暴后续观察的时间范围从3分钟到15小时后爆发触发。在红移测量是可用的,我们把限制的内在的高能量谱的爆发。

英文摘要:

The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is an atmospheric Cherenkov telescope (ACT) that uses a large mirror array to achieve a relatively low energy threshold. For sources with Crab-like spectra, at high elevations, the detector response peaks near 100 GeV. Gamma-ray burst (GRB) observations have been a high priority for the STACEE collaboration since the inception of the experiment. We present the results of 20 GRB follow-up observations at times ranging from 3 minutes to 15 hours after the burst triggers. Where redshift measurements are available, we place constraints on the intrinsic high-energy spectra of the bursts.
