论文摘要
高能峰峰的同步加速器驼峰通常位于0.1-10 KEV范围内，此类来源在X射线带中显示出极端的通量和光谱变化。各种光谱研究表明，高能量峰峰的X射线光谱是弯曲的，并通过对数 - 帕克代模型更好地描述。曲率归因于依赖能量的统计加速机制。在这项工作中，我们回顾了高能量峰的X射线光谱研究。发现对数 - 羟基蛋白酶模型在峰周围以宽的能量间隔很好地描述了光谱。对数 - 羟基蛋白酶模型提供了研究从其频谱参数之间的相关性的可能性。因此，我们汇总了从对数 - 促销模型得出的各种参数之间的相关性研究及其对描述Blazars的可变性机制的影响。
The synchrotron hump of the high energy peaked blazars generally lies in the 0.1-10 keV range and such sources show extreme flux and spectral variability in X-ray bands. Various spectral studies showed that the X-ray spectra of high energy peaked blazars are curved and better described by the log-parabolic model. The curvature is attributed to the energy dependent statistical acceleration mechanism. In this work, we review the X-ray spectral studies of high energy peaked blazars. It is found that the log-parabolic model well describes the spectra in a wide energy interval around the peak. The log-parabolic model provides the possibility of investigating the correlation between the spectral parameters derived from it. Therefore, we compiled the studies of correlations between the various parameters derived from the log-parabolic model and their implications to describe the variability mechanism of blazars.
