ALMA moment maps. From left to right: CO(2−1) integrated flux (moment-0), mean velocity (moment-1), and velocity dispersion maps (moment-2). Top panels show data with 0.2 arcsec angular resolution, while the lower panels show data with 0.6 arcsec resolution. Regions with emission below 3σ are blanked out. The synthesised beam of each dataset is shown by the grey filled ellipses in the lower-left corner of the map. In the bottom-left panel, arrows indicate the direction towards NGC 2993 and Arp 245 North.
