Scientific paper

The origin of the large luminosity of AGN remains unexplained but it is believed to derive from gravitational energy and is usually associated with an accretion disk circling a super-massive black hole. Recent work has raised the intriguing possibility 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 of the spheroid of normal early type galaxies formed.In this model, the broad permitted lines characteristic of the Broad Line Region (BLR) and their variability are originated in these cSNRs. Only a small fraction (about 5%) of the total mass of a normal spheroid, the core mass, is needed to participate in a burst to explain the observed luminosities and luminosity function of Quasars at z> 2.0
