The distribution of 12CO(1–0) has been mapped over the spiral galaxy NGC 253 using the Swedish-ESO Submillimetre Telescope (SEST). Emission was found to extend 22.4 arcmin along themajor axis and to be concentrated towards the nucleus with an LSR systemic velocity of 235 km s−1. The CO intensity and velocity distribution suggests three subsystems: a dense, highly-rotating nuclear cloud, a disk ...
