Ratio of HI-to-stellar masses of a sub-sample of local volume field galaxies (blue diamonds; 64 studied here out of the 96 with available DeCaLs imaging from Karachentsev et al. 2013); nine SAGA and 15 ELVES satellites (yellow stars; matched with the Durbala et al. (2020) and Zhu & Putman (2023) measurements, respectively); and the Fornax galaxies (purple pentagons; 17 studied here out of the 39 HI masses or upper limits reported in Kleiner et al. 2023) as a function of edge surface stellar mass density. The HI masses of the Fornax LTGs and ETGs are taken from Loni et al. (2021) when available (dark blue points). Higher edge densities are found when the H I-to-stellar masses ratios are lower. A best-fit to the data points is shown as a dashed line to highlight this trend.
