Scientific paper

We present results from the CO (J=1-0) BIMA Survey of Nearby Galaxies (SONG). The BIMA SONG includes 44 spiral (Sa-Sd) galaxies with MB < 11, VHEL < 2000 km s-1 , inclination < 70o and declination > -20o. The 30 galaxies for which CO emission is known to be extended were observed with a 7-field mosaic with a 3-4' FOV at 7" angular resolution and 5 km/s spectral resolution; the remaining 14 galaxies were observed with a single central pointing (FOV ~ 2'). In this poster, we also concentrate on the gas distribution in barred spirals and compare the observations to predictions of a secular evolution scenario in which late type bars evolve into early type bars.
