Scientific paper

The results of a study linking nuclear activity to galaxy morphology are reported. Those galaxies listed by Morgan (1958, 1959) as having peculiar nuclei are found to occur with equal frequency in barred, transition, and normal-type spiral galaxies, but tend to occur most frequently in early-type (S0/Sa) systems. These results disagree with those reported by Sersic and Pastoriza (1967) for galaxies with hot-spot and related nuclei. The tendency for early-type spirals to have morphologically peculiar nuclei may be related to a similar tendency for such systems to be Seyfert galaxies and have external rings.
