论文摘要
在这里，我们介绍了两个Seyfert 1星系中AGN的详细研究，Leda 3095839和VII ZW 244。在俄罗斯科学学院特殊天文学观测值（Sao RAS）的特殊天体天文台（SAO RAS）中，它们都在我们较早获得Smbhs Masses中观察到了它们。之后，在Sao Ras的BTA 6 M望远镜上观察到两个星系在光谱法和偏光模式中，并带有焦点还原剂Scorpio-2。已经测量了连续体和宽Balmer线的线性极化。发现（i）（i）在宽H-Alpha系列的Leda 3095839星系中没有赤道散射的迹象，我们能够估计来自连续极化水平的SMBH自旋和磁盘中的磁场强度的值； （ii）对于星系VII ZW 244，显示了赤道散射的存在，因此，SMBH的质量是独立测量的，获得了系统的倾斜角，并估计了自旋的值。
Here we present the detailed investigation of AGNs in two Seyfert 1 galaxies, LEDA 3095839 and VII Zw 244. Both of them were observed within the photometric reverberation mapping project in Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS), during which we earlier obtained the SMBHs masses. After that, both galaxies were observed in spectropolarimetric and polarimetric modes on the BTA 6 m telescope of the SAO RAS with the focal reducer SCORPIO-2. The linear polarization of the continuum and broad Balmer lines has been measured. It was found that (i) there were no signs of equatorial scattering in the LEDA 3095839 galaxy in the broad H-alpha line, and we were able to estimate the value of SMBH spin and the magnetic field strength in the disk from the level of continuum polarization; (ii) for the galaxy VII Zw 244, the presence of equatorial scattering was shown, due to which the mass of the SMBH was independently measured, the inclination angle of the system was obtained, and the value of the spin was estimated.
