Scientific paper

Based on examination of plates obtained with 0.5-m, 2.6-m, and 6.0-m telescopes, it is found that 620 galaxies exhibiting a UV excess include 59 objects with double or multiple nuclei. The encounter rate for these objects is shown to be significantly higher among galaxies with a UV excess than among other galaxies, indicating that the former have more active nuclei than the latter. A list and photographs of the galaxies with two or more nuclei are presented along with descriptions of the individual galaxies and a discussion of their morphology. The data indicate that on the average, the brightness of the galactic nuclei increases and structural details (filaments, ejecta, and so forth) appear more frequently with increasing separation between the components. It is noted that two of the galaxies with double nuclei are Type 1 Seyferts.
