摘要:

在一个大的混响映射(RM)活动的活动星系核(AGN)的吸积率高的系列论文报告的第六,我们提出了速度分辨的时间滞后的H $β$发射线在2012年$-$ 2013年的活动中观察到的9个对象。为了在分析速度分辨RM前校正视宁度和仪器引起的谱线展宽,我们采用Richardson-Lucy反褶积方法重建了它们的H $β$剖面。通过蒙特卡罗模拟验证了反褶积的正确性和有效性。九个对象中有五个显示出明显的速度依赖于时间延迟。Mrk 335和Mrk 486显示了气体流入的特征,而Mrk 142和MCG +06-26-012的宽线区域(BLR)的云倾向于径向流出。Mrk 1044与男性化动议的情况一致。其余四个的滞后不是速度可分辨的。超爱丁顿吸积大质量黑洞(SEAMBHs)的速度分辨RM表明,它们在BLR中具有运动学的多样性。与具有亚爱丁顿吸积率的活动星系核相比,我们没有发现SEAMBHs的BLR运动学有显著差异。

英文摘要:

In the sixth of the series of papers reporting on a large reverberation mapping (RM) campaign of active galactic nuclei (AGNs) with high accretion rates, we present velocity-resolved time lags of H$β$ emission lines for nine objects observed in the campaign during 2012$-$2013. In order to correct the line-broadening caused by seeing and instruments before the analysis of velocity-resolved RM, we adopt Richardson-Lucy deconvolution to reconstruct their H$β$ profiles. The validity and effectiveness of the deconvolution are checked out by Monte Carlo simulation. Five among the nine objects show clear dependence of time delay on velocity. Mrk 335 and Mrk 486 show signatures of gas inflow whereas the clouds in the broad-line regions (BLRs) of Mrk 142 and MCG +06-26-012 tend to be radial outflowing. Mrk 1044 is consistent with the case of virialized motions. The lags of the rest four are not velocity-resolvable. The velocity-resolved RM of super-Eddington accreting massive black holes (SEAMBHs) shows that they have diversity of the kinematics in their BLRs. Comparing with the AGNs with sub-Eddington accretion rates, we do not find significant differences in the BLR kinematics of SEAMBHs.
