Cumulative mass distribution of the stellar mass of galaxies inside filaments at z = 0 separated by environmental history. The thick grey line shows the corresponding distribution obtained when considering all galaxies in the simulated volume at z = 0. For comparison, the values for the field galaxies are also reported. In each panel, the results of the two-sample KS test comparing filament and field galaxies are reported, including both the KS statistic D and the corresponding p-value.
