摘要

x射线的可变性是活动星系核(AGN)的一个显著特性,并且发射的能量学和时间尺度决定了x射线的起源必须非常接近中心引擎。在这篇综述中,我讨论了AGN变异研究的两个基本主题。一是变率时间尺度与x射线光度的相关性,二是x射线光度曲线的结构。在每一种情况下,我首先回顾过去大约10年已知的旧结果,然后我讨论非常新的结果,这可能会迫使我们修改我们关于AGN x射线可变性起源的想法。请注意,我正在讨论非耀变体AGN的可变性。

X-Ray Variability in Active Galactic Nuclei: Two Things That Everybody Should Know
X-ray variability is a distinguishing property of Active Galactic Nuclei (AGN), and the energetics and time scales of the emission dictate that the X-rays must originate very close to the central engine. In this review I discuss two basic topics from AGN variability research. The first is the correlation of the variability time scale with the X-ray luminosity, and the second is the structure of the X-ray light curve. In each case, I first review the old results that have been known for approximately the last 10 years and then I discuss very new results which may force us to modify our ideas about the origin of AGN X-ray variability. Note that I am discussing the variability of non-blazar type AGN.
