Abstract
We have been carrying out a CO J =1-0 large-scale survey of molecular gas along the galacti plane with NANTEN radio telescope at Las Campanas observatory Chile since 1996. More than 1,100,000 spectra have been obtained at a 4′ grid spacing for ∣b∣ ≤ 5° and at a 8′ grid spacing for 10° > ∣b∣ > 5°, respectively. In addition to having obtained a considerably improved better- sampled dataset for the CO clouds in the galactic disk, we have revealed new features outside the disk including molecular supershells, some peculiar off-plane structures in the galactic center region, and distant molecular clouds located in the galactic warp. I will briefly review some of the notable topics of the NANTEN CO galactic plane survey.
