Abstract:
The detailed morphology of the interstellar medium (ISM) in the
central kiloparsec of galaxies is controlled by pressure and
gravitation. The combination of these forces shapes both circumnuclear
star formation and the growth of the central, supermassive black hole.
We present visible and near-infrared Hubble Space Telescope images and
color maps of 123 nearby galaxies that show the distribution of the
cold ISM, as traced by dust, with excellent spatial resolution.
These observations reveal that nuclear dust spirals are found in
the majority of active and inactive galaxies and they possess a
wide range in coherence, symmetry, and pitch angle. We have used
this large sample to develop a classification system for
circumnuclear dust structures.

Note (1): Notes on Bar as follows:
1 = Bar in RC3 (Cat. VII/155) or other survey.
2 = Weak bar in RC3 (Cat. VII/155) .
3 = Bar classification unknown.
4 = Unbarred at visible wavelengths, e.g., RC3 (Cat. VII/155) .
5 = Unbarred in NIR image.
All galaxies with flags 1 and 2 were included in the barred sample;
those with class 4 or 5 were included in the unbarred sample.
Galaxies in class 3 were not included in the bar discussion.
Note (2): All galaxies with "No" are considered to be inactive.
