AGN as Starbursts: modelling the multifrequency spectrum
The starburst scenario for ordinary AGN postulates that nuclear activity is the direct consequence of the evolution of a starburst in the high metallicity and high density interstellar medium of the nuclear regions of galaxies. The broad line region (BLR) observed in Seyfert type 1 and QSOs is originated in a population of supernova (SN) and supernova remnants (SR) evolving in the high density gas of the nuclear environment. Using a theoretical approach, the multifrequency spectrum of a burst of star formation is computed as the sum of the young stellar component and the SN and SR component. The resulting spectrum of a burst of about 40 Myr of age is remarkably similar to the average AGN spectrum.
