| Abstract: |
Molecular gas makes an important contribution to the evolution of spiral galaxies, through star formation, bar inflows, and potential fueling of non-stellar sources in galaxy nuclei. However, it has been difficult (until recently) to gain enough information for generalized studies of the distribution and kinematics of molecular gas on size scales suitable for comparison with star forming regions or nuclear sources of interest. In this presentation, I discuss some of the important infrastructure developed by earlier single-dish studies, and highlight some recent interferometric studies that are expanding our knowledge of molecular gas on subkiloparsec scales in nearby spirals. In particular, I present a recent analysis of the radial distributions of molecular gas in nearby spiral galaxies from the BIMA CO Survey of Nearby spiral Galaxies (BIMA SONG). |
