Abstract:
We describe an on-going HST program aimed at determining the relationship
between the nuclear black hole mass and bulge mass in spiral galaxies. We have
selected a volume limited sample of 54 nearby spiral galaxies for which we
already have ground based emission line rotation curves, CCD surface photometry
and radio maps. We are now obtaining HST/STIS longslit observations of each of
the galaxies in the sample in order to determine the nuclear Halpha rotation
curve at high (~0.1") spatial resolution. We will use these data to measure the
unresolved dark mass concentration at the nucleus of each object. Here we show
the first results from observations of objects in the sample.
