Scientific paper

The starburst-warmers scenario for Active Galactic Nuclei postulates that the observed nuclear activity is the direct consequence of the evolution of a starburst in the high metallicity and high density interstellar medium in the nuclear regions of galaxies. The broad line region observed in Seyfert type 1 and quasi-stellar objects is originated in a population of young supernova remnants evolving in the high density gas of the nuclear environment. During the supernova (SN) stage, when the ionizing flux is dominated by SN activity much variability is expected in objects with SN rates of ≡1 yr-1. The author reviews recent observational results that provide supporting evidence to this scenario. In particular, the peculiar SNe 1987F and 1988I have optical properties that closely resemble those of Seyfert 1 nuclei.
