High-resolution CO observations of NGC 1068
High-resolution CO observations of the central 60 arcsec x 60 arcsec of the Seyfert/starburst galaxy NGC 1068 have been performed, and the results are reported. The CO distribution within the central disk consists of the disk, northeast and southwest component located in optically red, dusty areas. The former coincides with a radio plateau and far-IR source, and the latter two coincide with regions of strong 10 micron emission. The total H mass is estimated to be 5.6 x 10 to the 9th solar masses. The CO velocity field reveals a peculiar structure in that the isovelocity contours run primarily parallel to the position angle of 82 deg. The velocity contours indicate that there are large-scale noncircular motions in the CO molecular clouds. The CO line-width map reveals a good coincidence between regions of broad CO line profiles and the northeast and southwest radio lobes, suggesting a physical relation between the molecular gas and relativistic plasma in the lobes. 44 references.
