Mapping circumnuclear dust in nearby galaxies

Hubble Space Telescope observations have revealed a wealth of dust structure in the circumnuclear regions of galaxies and provide the highest-resolution maps of their cold ISM. These circumnuclear dust structures are of substantial interest for the study of mass transport in galaxies, particular secular evolution, fueling central starbursts, and nuclear accretion onto supermassive black holes. In this review I concentrate on several instances where feedback processes in galaxies appear to have substantially affected the morphology and kinematics of the circumnuclear ISM and discuss the implications of this work for future studies, particularly with ALMA.
