Abstract The mass measurement of supermassive black holes (SMBHs) is a very complex task. Between several methods for SMBH mass measurements, some of them use the spectral lines, which indicate the motion of the emitting/absorbing material around an SMBH. Mostly, there is an assumption of virialization of line emitting gas in the region which is close to the central SMBH. In this paper we will give an overview of methods for the SMBH mass measurements using broad emission spectral lines observed in Type 1 AGNs. First we give the basic idea to use the parameters of broad lines to SMBH mass measurements. After that we give an overview of broad lines from X-ray (Fe kα) to the IR (Pashen and Brecket lines) which have been used for SMBH mass estimates. Additionally, we describe and discuss a new method for SMBH mass measurements using the polarization in the broad lines emitted from Type 1 AGNs.

AGN 中的宽谱线和超大质量黑洞质量测量

摘要 超大质量黑洞（SMBH）的质量测量是一项非常复杂的任务。在几种 SMBH 质量测量方法之间，其中一些使用谱线，表明发射/吸收材料围绕 SMBH 的运动。大多数情况下，在靠近中央 SMBH 的区域中存在管线排放气体的虚拟化假设。在本文中，我们将概述使用在 1 型 AGN 中观察到的宽发射谱线进行 SMBH 质量测量的方法。首先，我们给出了将宽线参数用于 SMBH 质量测量的基本思想。之后，我们概述了从 X 射线 (Fe kα) 到用于 SMBH 质量估计的 IR（Pashen 和 Brecket 线）的宽线。此外，
