摘要:

一个高采样率,多个月的混响映射活动,主要是在MDM天文台进行的支持观测来自世界各地的望远镜的数据的详细分析,揭示了几个附近活动星系核的宽线区域(BLR)内的H β发射区表现出各种运动学行为。虽然这项活动的主要目标是获得新的或改进的Hbeta混响滞后测量几个相对较低的光度AGN(在一个单独的工作),我们也能够明确地重建速度分辨混响信号从我们的目标的一个子集。通过对NGC 3227、NGC 3516和NGC 5548核区域中观测到的光学连续谱和宽的H β发射线变化的高节奏光谱监测,我们分别清楚地看到了流出、下落和维里化BLR气体运动的证据。

英文摘要:

A detailed analysis of the data from a high sampling rate, multi-month reverberation mapping campaign, undertaken primarily at MDM Observatory with supporting observations from telescopes around the world, reveals that the Hbeta emission region within the broad line regions (BLRs) of several nearby AGNs exhibit a variety of kinematic behaviors. While the primary goal of this campaign was to obtain either new or improved Hbeta reverberation lag measurements for several relatively low luminosity AGNs (presented in a separate work), we were also able to unambiguously reconstruct velocity-resolved reverberation signals from a subset of our targets. Through high cadence spectroscopic monitoring of the optical continuum and broad Hbeta emission line variations observed in the nuclear regions of NGC 3227, NGC 3516, and NGC 5548, we clearly see evidence for outflowing, infalling, and virialized BLR gas motions, respectively.
