引力微透镜对类星体宽吸收线的影响:Fe K $α$线的情况

Influence of gravitational microlensing on broad absorption lines of QSOs: The case of the Fe K$α$ line

Predrag Jovanović, Luka Č. Popović, Saša Simić

摘要:

在这里,我们给出了一个简要的概述引力微透镜对透镜类星体宽吸收谱线的影响的一些调查。特别地,我们考虑了微透镜效应对Fe K $α$宽吸收线的影响,采用吸收区覆盖的吸积盘模型。采用光线打靶法模拟引力微透镜效应,得到了真实的微透镜图案。得到了微透镜效应对谱线的发射和吸收分量都有影响,且影响程度取决于发射和吸收谱线区域的尺寸。在这里,我们给出了详细的分析,由于引力微透镜的发射和吸收线形状的变化。

英文摘要:

Here we give a brief overview of some investigations of the gravitational microlensing influence on broad absorption spectral lines of lensed QSOs. Especially, we consider the microlensing influence on the Fe K$α$ broad absorption lines using a model of an accretion disk covered by an absorption region. Gravitational microlensing is modeled by ray shooting method which enables us to obtain realistic microlensing patterns. We obtain that microlensing can affect both emission and absorption component of line that depends on dimensions on emission and absorption line regions. Here we give detailed analysis of emission and absorption line shape variations due to gravitational microlensing.
