摘要

我们研究了从选定的活动星系核观测到的高能γ射线强度的变化。切伦科夫望远镜收集的公开数据通过一种简单的方法进行了检验,该方法仅利用源事件和背景事件的数量。我们的结果指出,从所调查的来源观察到的信号有一定程度的时间变化。当与从其他观测推断出的源强度相比较时,发现有几项测量在源事件的数量上有过多或不足之处。

Variability of VHE γ–ray sources

We study changes in the γ–ray intensity at very high energies observed from selected active galactic nuclei. Publicly available data collected by Cherenkov telescopes were examined by means of a simple method utilizing solely the number of source and background events. Our results point to some degree of time variability in signal observed from the investigated sources. Several measurements were found to be excessive or deficient in the number of source events when compared to the source intensity deduced from other observations.
