On the formation of disk galaxies and massive central objects.

SELLWOOD J.A. and MOORE E.M.

Abstract (from CDS):

We propose that massive central objects form in the centers of the bars that must develop in young high surface density galactic disks. Large-scale dynamics shut off the growth of the central mass before it reaches ∼2% of the disk mass at the time, but this mass is sufficient to substantially weaken the bar. Subsequent evolution of the galaxy can either complete the destruction of the bar or cause it to recover, depending on the angular momentum distribution of later infalling material. We produce massive, fully self-gravitating disks having roughly flat rotation curves that are quite stable. If at least part of the central masses we require constitute the engines of QSOs, then our picture naturally accounts for their redshift dependence since the fuel supply is shut off by the development of an inner Lindblad resonance. A prediction is that massive objects should not be found in halo-dominated galaxies such as low-luminosity or low surface brightness galaxies.
