Face-on and edge-on projected gas density (first two panels, respectively) and the corresponding (O/H) (two right panels) distributions for three selected galaxies of the CIELO-P7 sample: 0181, 2627, and 7805, taken as examples. Each row shows a galaxy at a key stage of its evolution where gas outflows are detected. The M_* of the galaxies at redshift z = 0 is shown in each plot. The streamlines depict the median velocity direction of the gas components. The first two galaxies are more rotationally dominated, while the third galaxy has a complex gas structure resulting from a recent gas-rich interaction.
