论文摘要
我们使用Fermi/LAT（3LAC）和伽马射线窄线Seyfert 1星系（Gamma-Nlsy1s）检测到的第三个Blazars目录来研究它们之间的播出序列及其之间的关系。我们的结果如下：（i）Fermi Blazars和Gamma-Nlsy1s的同步加速器峰频率和峰值光度之间存在弱的抗相关性，该抗相关性支持Blazar序列。然而，在多普勒校正后，反相关消失了，这表明同步加速器峰频率和峰光度之间的抗相关性受到光束效应的影响。 （ii）Fermi Blazars和Gamma-Nlsy1s的JET动力和同步加速器峰频率之间存在明显的抗相关性，这表明Gamma-Nlsy1s可以很好地适合原始的Blazar序列。 （iii）根据先前的工作，可以通过统计或随机加速机制来解释同步加速器峰频率与同步加速器曲率之间的关系。对于整个样品，费米大麻和BL LACS的同步加速器峰频率和同步加速器曲率之间存在显着相关性。相关的斜率与统计加速度一致。对于FSRQ，LBL，IBL，HBLS和GAMMA-NLS1S，我们也发现了显着的相关性，但是在这些情况下，斜率无法通过以前的理论模型来解释。 （iv）γ-NLS1中的同步加速器峰频率与同步加速器曲率之间的关系斜率大于FSRQ和BL LAC的斜率。该结果可能意味着冷却在FSRQ和BL lac的加速过程中占主导地位，而伽马NLS1则相反。
We use the third catalog of blazars detected by Fermi/LAT (3LAC) and gamma-ray Narrow-line Seyfert 1 Galaxies (gamma-NLSy1s) to study the blazar sequence and relationship between them. Our results are as follows: (i) There is a weak anti-correlation between synchrotron peak frequency and peak luminosity for both Fermi blazars and gamma-NLSy1s, which supports the blazar sequence. However, after Doppler correction, the inverse correlation disappeared, which suggests that anti-correlation between synchrotron peak frequency and peak luminosity is affected by the beaming effect. (ii) There is a significant anti-correlation between jet kinetic power and synchrotron peak frequency for both Fermi blazars and gamma-NLSy1s, which suggests that the gamma-NLSy1s could fit well into the original blazar sequence. (iii) According to previous work, the relationship between synchrotron peak frequency and synchrotron curvature can be explained by statistical or stochastic acceleration mechanisms. There are significant correlations between synchrotron peak frequency and synchrotron curvature for whole sample, Fermi blazars and BL Lacs, respectively. The slopes of the correlation are consistent with statistical acceleration. For FSRQs, LBLs, IBLs, HBLs, and gamma-NLS1s, we also find a significant correlation, but in these cases the slopes can not be explained by previous theoretical models. (iv) The slope of relation between synchrotron peak frequency and synchrotron curvature in gamma-NLS1s is large than that of FSRQs and BL Lacs. This result may imply that the cooling dominates over the acceleration process for FSRQs and BL Lacs, while gamma-NLS1s is the opposite.
