AGN PG 0052+251中间宽线区的进一步证据

More Evidence for the Intermediate Broad Line Region of the Mapped AGN PG 0052+251

XueGuang Zhang

摘要:

在手稿中,建议的中间BLR的性质检查映射AGN PG 0052+251。考虑到He { \sc ii}宽谱线对观测到的H $β$宽谱线的明显影响,我们仔细地确定了观测到的H $α$宽谱线和H $β$宽谱线的谱线参数(特别是线宽和谱线通量)。基于测得的谱线参数,对每个观测到的宽巴耳末谱线采用两个宽分量的模型是优选的,然后通过计算内/中间宽分量的不同时滞以及由内和中间宽分量的性质确定的相应维里BH质量比来证实该模型。然后,针对两个宽分量检查宽线宽度和宽线通量之间的相关性:一个明显强的负相关性用于内部宽分量,但是一个正相关性用于中间宽分量。两种宽组分的不同相关性强烈支持PG 0052 +251的中间BLR。

英文摘要:

In the manuscript, the properties of the proposed intermediate BLR are checked for the mapped AGN PG 0052+251. With the considerations of the apparent effects of the broad He {\sc ii} line on the observed broad H$β$ profile, the line parameters (especially the line width and the line flux) of the observed broad H$α$ and the broad H$β$ are carefully determined. Based on the measured line parameters, the model with two broad components applied for each observed broad balmer line is preferred, and then confirmed by the calculated much different time lags for the inner/intermediate broad components and the corresponding virial BH masses ratio determined by the properties of the inner and the intermediate broad components. Then, the correlation between the broad line width and the broad line flux is checked for the two broad components: one clearly strong negative correlation for the inner broad component, but one positive correlation for the intermediate broad component. The different correlations for the two broad components strongly support the intermediate BLR of PG0052+251.
