以赛弗特星系为例,考虑活动星系核的物质成分和特殊几何结构,通过建立电子散射模型来研究活动星系核的光学偏振,给出与观测结果相一致的偏振值,以及偏振度随视角变化的特性,对进一步研究活动星系核的统一模型有一定意义。
An electron scattering model is proposed to explain the polarization of AGN (active galactic nuclei) in terms of its specific geometry and particle distribution, for example, Seyfert galaxy. The model prediction, such as the degree of polarization and its variation with inclination angles, is consistent with the observations.
