Recent Results of CO Observations of IC342, NGC6946, Maffei2, and M51 with the NMA

Abstract
We present our recent results of high spatial resolution(2″-6″) CO and 13CO(J=1−0) observations with the Nobeyama Millimeter Array(NMA). We observed the central (1-2 kpc) regions of nearby galaxies, IC342, Maffei2, and NGC6946 with 2″-4″ resolution (45-90 pc) in CO and 13CO, and the 3' region of M51 with 4″-6″ resolution (180-280 pc). We discuss the structures and kinematics of molecular gas in the central region of nearby late-type spiral galaxies, and in spiral arms, and discuss the trigger of star formation from viewpoints of galactic shock, gas fueling by bars.
