• To study the interstellar medium and the interplay between the atomic and molecular components in a low-metallicity environment, we present a complete high angular and spectral resolution map and position-position-velocity data cube of the [sup 12] CO(J = 2-1) emission from the Local Group galaxy Messier 33. Its metallicity is roughly half-solar, such that we can compare its interstellar medium with that of the Milky Way with the main changes being the metallicity and the gas mass fraction. Using the CO(2-1) emission to trace the molecular gas, the probability distribution function of the H[sub 2] column density shows an excess at high column density above a log-normal distribution.
