Abstract: |
Using a sample of 7 barred spirals from the BIMA Survey of Nearby Galaxies (SONG), we compare the molecular gas distribution in the bar, to recent massive star formation activity. In all 7 galaxies, Hα is offset azimuthally from the CO on the downstream side. The maximum offset, at the bar ends, ranges from 170-570 pc, with an average of 320+/-120 pc. We discuss whether the observed offsets are consistent with the description of gas flows in bars provided by the two main classes of models: N-body models and hydrodynamic models. |
