论文摘要

We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring Project 2016 sample, drawing inferences on the geometry and structure of the low-ionization broad-line region (BLR) and the mass of the central supermassive black hole.总体而言，我们发现H \ b {eta} BLR通常是在低至中度倾斜角处观察的厚磁盘。我们将样本与先前的研究相结合，并研究线形形状依赖性（例如Log10（FWHM/σ）），在BLR结构和运动学上，并搜索任何依赖BLR的光度依赖性趋势。我们发现使用根平方谱时，在宽H \ b {eta}发射线的轮廓形状与爱丁顿比率之间存在反相关的边际证据。但是，我们没有发现任何依赖光度的趋势，并得出结论，AGN具有不同的BLR结构和运动学，这与瞬态AGN/BLR条件的假设一致，而不是系统的趋势。

We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring Project 2016 sample, drawing inferences on the geometry and structure of the low-ionization broad-line region (BLR) and the mass of the central supermassive black hole. Overall, we find that the H\b{eta} BLR is generally a thick disk viewed at low to moderate inclination angles. We combine our sample with prior studies and investigate line-profile shape dependence, such as log10(FWHM/σ), on BLR structure and kinematics and search for any BLR luminosity-dependent trends. We find marginal evidence for an anticorrelation between the profile shape of the broad H\b{eta} emission line and the Eddington ratio, when using the root-mean-square spectrum. However, we do not find any luminosity-dependent trends, and conclude that AGNs have diverse BLR structure and kinematics, consistent with the hypothesis of transient AGN/BLR conditions rather than systematic trends.
