AGN as Starbursts: modelling the multifrequency spectrum

  • Roberto Terlevich
Part of the Astrophysics and Space Science Library book series (ASSL, volume 160)


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.
