Description
The Starburst model for radio-quiet Active Galactic Nuclei (AGN)
postulates that the activity seen in most AGN is powered solely by young
stars and compact supernova remnants (cSNR) in a burst of star formation
at the time when the metal rich core of the spheroid of a normal early
type galaxy was formed. In this model, the broad permitted lines
characteristic of the Broad Line Region (BLR) and their variability
originate in these cSNR. Detailed calculations of strong radiative
cooling behind supernova shock waves evolving in a high density medium,
combined with static photoionization computations, have shown that cSNR
can reproduce most of the basic properties of the BLR in low luminosity
AGN. The authors make definite predictions about the lag, the observed
delay between sudden changes in the continuum ionizing radiation
followed, after some time, by changes in the intensity of the emission
lines from the broad line region of AGNs. The authors have proposed that
QSOs are the young metal rich cores of massive elliptical galaxies
forming at z > 2.0. They predict that the progenitors of QSOs should
look like dusty starbursts and be about 4 times more luminous (in
bolometric units) and 10 times less frequent than QSOs themselves.
