摘要:

作为大型混响映射系列论文之一,我们利用最大熵方法(MEM)对2012-2013年间观测到的9个具有超爱丁顿吸积率的窄线Seyfert 1星系进行了Hβ和Hγ发射线的速度延迟图的研究。用MEM方法可靠地重建了6个天体的谱图,Mrk 335的Hβ和Hγ谱线表明其宽线区(BLR)的气体正在下落。Mrk 142的Hβ和Hγ谱线显示出外流特征。Mrk 1044的Hβ和Hγ图显示了复杂的运动学--伴随着外流特征的维里化运动,IRAS F12397+3333的Hβ图与盘或球壳一致。Mrk 486和MCG +06-26-012的Hβ图谱分别提示存在流入和流出。这些超爱丁顿吸积体表现出不同的几何和运动学。简要讨论他们的BLR提供了每个单独的对象。

英文摘要:

As one of the series of papers reporting on a large reverberation mapping campaign, we apply the maximum entropy method (MEM) to 9 narrow-line Seyfert 1 galaxies with super-Eddington accretion rates observed during 2012-2013 for the velocity-delay maps of their Hβ and Hγ emission lines. The maps of 6 objects are reliably reconstructed using MEM. The maps of Hβ and Hγ emission lines of Mrk 335 indicate that the gas of its broad-line region (BLR) is infalling. For Mrk 142, its Hβ and Hγ lines show signatures of outflow. The Hβ and Hγ maps of Mrk 1044 demonstrate complex kinematics -- a virialized motion accompanied by an outflow signature, and the Hβ map of IRAS F12397+3333 is consistent with a disk or a spherical shell. The Hβ maps of Mrk 486 and MCG +06-26-012 suggest the presence of an inflow and outflow, respectively. These super-Eddington accretors show diverse geometry and kinematics. Brief discussions of their BLRs are provided for each individual object.
