Scientific paper

The relative strengths of J = 1→0 12CO, 13CO, and C18O and J = 2→1 12CO lines indicate that the CO emission from M82 is optically thin compared to other galaxies. A 30 point map of 12CO J = 1→0 spectra taken on a 30arcsec grid with a 100arcsec beam is presented, along with major- and minor-axis spatial velocity diagrams. There seems to be CO emission on the minor axis that is spatially extended beyond the stellar disk. This emission may originate in the dusty filaments above and below the stellar disk.
