Using ~1-2 kpc scale Atacama Large Millimeter Array observations of CO(3-2) and CO(4-3), we characterize the CO(4-3)/CO(3-2) line ratios of local analogues of main-sequence galaxies at z ~ 1-2, drawn from the DYnamics of Newly Assembled Massive Objects (DYNAMO) sample. We measure CO(4-3)/CO(3-2) across the disk of each galaxy and find a median line ratio of R 43 = 0.54 +0.16−0.15 for the sample.
