摘要

我们估算了 42 个红色类星体样本的自旋、质量和倾角值。我们的估算结果表明，有两个天体爱丁顿比值最高的两个天体：F2MS J1113+1244 和 F2MS J1434+0935，可能具有几何厚度的圆盘。六个天体SDSS J0036-0113、S82X 0040+0058、S82X 0118+0018、S82X 0303-0115、FBQS J1227+3214、S82X 2328-0028可能存在 "逆行 "旋转。对估计自旋值的分析表明，红色类星体群中可能包含赛弗星系和 NLS1。

Red Quasars: Estimation of SMBH Spin, Mass, and Accretion Disk Inclination Angle

We estimated values of spin, mass, and inclination angle for sample of 42 red quasars. Our estimations show that two objects: F2MS J1113+1244 and F2MS J1434+0935 with the highest Eddington ratios may have geometrically thick disk. Six objects: SDSS J0036-0113, S82X 0040+0058, S82X 0118+0018, S82X 0303-0115, FBQS J1227+3214, S82X 2328-0028 may have “retrograde” rotation. Analysis of estimated spin values shows that red quasar population may contain Seyfert galaxies and NLS1.

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
