Quasars as events in the nuclei of galaxies: the evidence from direct photographs

Similarities between quasars and the nuclei of N galaxies and Seyfert galaxies suggest that quasars may also occur in galaxy nuclei. 200-inch direct photographs of quasars are consistent with this hypothesis. Those quasars which are predicted to show underlying galaxies do so, and those which are predicted not to show underlying galaxies do not.
