Comparison between depletion timescale due to outflows and gas consumption due to star formation. DGS galaxies from this work are shown as circles. The typical uncertainty on both timescales is shown in the top right corner. Squares, stars, and pentagons are the results from local AGNs, starburst galaxies, and LINERs, respectively (Cicone et al. 2014). The dashed line reports the 1:1 relation. The area below this line is populated by galaxies whose outflows are more efficient than star formation in consuming gas (i.e., τ_dep, out < τ_dep, SF). All data are color-coded for their mass-loading factors.
