| Abstract: |
NGC 1808 is a nearby (10 Mpc) starburst galaxy with a superwind detected as a dust outflow from the nuclear region. In order to study the evolution of molecular clouds in the feeding and feedback processes related to the starburst activity, we have carried out observations with ALMA and ASTE telescopes. We present preliminary results of cycle 1 (12-m array) large-field CO (1-0) imaging with ALMA and 1-mm line observations with ASTE. Molecular gas was detected and resolved at a resolution of 2” (∼100 pc) throughout the galactic disk. This first high-resolution CO image of NGC 1808 reveals: a circumnuclear disk in the center, 500-pc starburst ring, indication of inflow and outflow motion, giant molecular clouds (GMCs) and associations (GMAs) in the spiral arms and bar. |
