Active Galactic Nuclei among Polar-Ring Galaxies
D. V. Smirnov, V. P. Reshetnikov
Abstract
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.
