Gas phase distribution of surrounding gas cells of the seven gas-deficient satellites during the last 200 Myr before the gas removal. The distributions are weighted by the external pressure contributed by individual surrounding gas cells. The satellites are grouped into two categories based on the properties of the surrounding gas: those embedded in hot and low-density gas (left panel), and those surrounded by cold and dense gas (right panel). In each panel, the 1σ distributions of the surrounding gas in the phase diagram for individual galaxies are shown in different colors. The background density map displays the full surrounding gas phase distribution for a single satellite in each case (shown in black) as a reference. Gas-deficient satellites in the left panel are likely stripped by classical ram pressure, whereas those in the right panel are affected by interactions with nearby cold and dense gas structures.
