Molecular bar and star formation in the nucleus of NGC 6946

We have observed the bright, nearby galaxy NGC 6946 in the 2.6 mm line of CO with the Owens Valley Millimeter-Wave Interferometer, synthesizing a beam 7''.6 by 5''.4. The molecular gas in the central 1.5 kpc of the galaxy is confined to a bar of extent approx.2700 pc by 550 pc, which is centered on the nucleus and connects two dust lanes in the innermost spiral arms. The molecular bar is the likely source of the star formation activity suggested by optical and infrared studies in the nucleus of NGC 6946.
