Abstract

Based on SDSS data, we consider the fraction of active galactic nuclei among polar-ring galaxies. We have found evidence for an excess of Seyfert galaxies and LINERS among polar-ring galaxies compared to ordinary objects. The observed nuclear activity of polar-ring galaxies may be associated with the accretion of gas from the region of the polar structures onto the central galaxies.

极环星系中的活跃银河核

摘要

基于SDSS数据，我们考虑了极环星系中活跃的银河核的比例。我们发现有证据表明，与普通天体相比，极环星系中有过多的赛弗特星系和LINERS。观察到的极环星系的核活动可能与气体从极地结构区域到中央星系的积聚有关。
