论文摘要
由于紧凑性，活性银河核（AGN）仍未通过光学观测来解决。但是，在其中心部分的结构和物理条件对于研究物质吸收到超级质量黑洞的过程尤为重要，最终这些研究对于了解星系进化至关重要。极化包含有关电磁波与环境之间相互作用的信息，并提供了有关AGN中心区域中物理过程的信息，这些信息借助其他光学观测值无法找到。在本文中，讨论了在偏光光中活跃银河核（AGN）中的几何形状，运动学和物理过程的研究的重要性。概述了极化形成的机理，它们与不同的结构和尺度的联系。此外，我们根据俄罗斯科学院特殊天体物理观察员进行的观察结果进行了不同的假设，概述了偏振学研究。
Due to the compactness active galactic nuclei (AGNs) are still unresolved with optical observations. However, structure and physical conditions of the matter in their central parts are especially important to study the processes of the matter accretion to supermassive black holes and eventually these investigations are essential to understand the galaxy evolution. Polarization contains information about the interaction of electromagnetic waves with the environment and provides information about the physical processes in the central regions of the AGNs that could not be found with the help of other optical observations. In this paper, the importance of applying polarimetry methods to the study of geometry, kinematics, and physical processes in active galactic nuclei (AGN) in polarized light is discussed. An overview of the mechanisms of polarization formation, their connection with different structures and scales are provided. Also, we overview the polarimetric investigations based on different assumptions that are done using the observations conducted in Special Astrophysical Observatory of the Russian Academy of Sciences.
