论文摘要
Blazars代表了宇宙中巨大的$γ$ ray来源的主要人口。这些来源在从无线电到TEV $γ$ rays的整个电磁频谱中表现出一些特性，例如强和非热连续发射，所有时间标准都具有快速变化。无线电和光波长的发射高度极化，并具有显着变化。在耀斑活性期间观察到大弹性发射的最快变异性，这是大烈士的重要观察性质。在本文中，我们描述了各种方法，以表征大麻的多波长光曲线中的时间变异性。我们还提供了一组统计参数的详细说明，用于量化时间序列中存在的可变性水平。还讨论了从变异性研究中得出的信息的含义，还讨论了使用多波长观测值探测大麻物理的含义。
Blazars represent dominant population of the extragalactic $γ$-ray sources in the Universe. These sources exhibit some characteristic properties like strong and non-thermal continuum emission over the entire electromagnetic spectrum from radio to TeV $γ$-rays with rapid variability on all timescales. The emission at radio and optical wavelengths is highly polarized with significant variation. The fastest variability in the blazar emission is observed during the flaring activity which is an important observational property of blazars. In this paper, we describe various methods to characterize the temporal variability in the multi-wavelength light curves of blazars. We also provide a detailed description of the set of statistical parameters which are used to quantify the level of variability present in the time-series. Implications of the informations derived from the variability study to probe the physics of blazars using multi-wavelength observations are also discussed.
