Scientific paper

In an unbiased sample of nearby E/S0 galaxies we discovered 6 new stellar nuclear disks, in addition to 3 discovered in earlier work. These disks are ideal tools for measuring central black hole masses, and the one earlier case studied spectroscopically, NGC 4342, showed an unusually high M_bh/M_bulge ratio. Another, NGC 4570, shows a series of rings of anomalous color and morphology which seem to be fossils of an episode of mass accretion, bar formation, dynamical resonances, and bar dissolution into a bulge. We propose STIS spectroscopy and WFPC2 imaging of an additional 4 of these galaxies to: {1} test whether the unusual M_bh/M_bulge ratio is typical of these nuclear disk galaxies and {2} search for additional ring/bar structures will help determine the source of the accreted material and the time sequence of the disk/bar/bulge/Black Hole fueling connection.
