类星体吸收线红移的研究(英文)

A Study of Absorption Redshifts of Quasars

在此工作中,分析了一个类星体样本的吸收线红移和发射线红移之间的关系。结果表明这两类红移之间存在显著的相关。主要结论:a)反常吸收线红移的主要部分是宇宙学红移;b)吸收体相对于类星体的运动是弱的;c)结果表明产生这些反常吸收线红移的吸收体位于类星体寄主星系或者类星体内部并且朝着类星体运动。

In this work, we employ a sample of quasars with some of their absorption redshifts larger than their emission redshifts and make a correlation analysis between the two quantities. The analysis reveals a very significant correlation between the two kinds of redshfits. Our study leads to the following conclusions： a） the main part of these anomalous absorption redshifts must be the cosmological one; b） the relative motion of the absorbers of quasars is mild; c） it is suggested that the absorbers producing the anomalous absorption redshifts must be inside the host galaxies or quasars and move towards the corresponding quasars.
