Evolution of broad-line emission from active galactic nuclei.

ELITZUR M., HO L.C. and TRUMP J.R.

Abstract (from CDS):

Apart from viewing-dependent obscuration, intrinsic broad-line emission from active galactic nuclei (AGN) follows an evolutionary sequence: type 1 ⟶ 1.2/1.5 ⟶ 1.8/1.9 ⟶ 2 as the accretion rate on to the central black hole is decreasing. This spectral evolution is controlled, at least in part, by the parameter Lbol/M2/3, where Lbol is the AGN bolometric luminosity and M is the black hole mass. Both this dependence and the double-peaked profiles that emerge along the sequence arise naturally in the disc-wind scenario for the AGN broad-line region.
