论文摘要
在这里，我们研究了发射H $β$和H $α$发射线的活性银河核（AGN）中宽线区域（BLR）部分的运动学。我们探讨了宽H $β$和H $α$发射线的宽度和不对称的高质量（即高信号与噪声比）的样本中的1型AGN的光谱，从Sloan数字天空调查的数据释放16中获取，以便探索与重力限制运动的可能偏差。为了仅找到H $β$和H $α$的广泛组成部分，我们使用幻想（全自动Python工具进行AGN光谱分析）代码AGN光谱的多组分建模以及仔细提取宽发射线参数。我们表明，基于宽线曲线宽度和不对称，发射H $β$和H $α$线的BLR气体遵循类似的运动学，并且似乎在我们的1型AGN样品中被病毒。
Here we investigate the kinematics of the part of the broad line region (BLR) in active galactic nuclei (AGNs) emitting H$β$ and H$α$ emission lines. We explore the widths and asymmetries of the broad H$β$ and H$α$ emission lines in a sample of high quality (i.e. high signal to noise ratio) spectra of type 1 AGN taken from the Data Release 16 of the Sloan Digital Sky Survey, in order to explore possible deviation from the gravitationally bound motion. To find only the broad component of H$β$ and H$α$ we use the FANTASY (Fully Automated pythoN Tool for AGN Spectra analYsis) code for the multi-component modeling of the AGN spectra and for careful extraction of the broad emission line parameters. We show that based on the broad line profiles widths and asymmetries, the BLR gas emitting H$β$ and H$α$ lines follows similar kinematics, and seems to be virialized in our sample of type 1 AGN.
