Mass-loading factors as a function of stellar mass using the unbound outflows and expelled mass rates. The reported relation by Muratov et al. (2015) $\eta \propto M_{\ast }^{-0.35}$. Symbols are described in Fig. 8 except for FIRE-2 simulation measurements by Pandya et al. (2021, black cross) and for observational estimations for massive, compact, and starburst galaxies at z = 0.4 − 0.7 by Perrotta et al. (2023, black diamonds). For visualisation purposes the median values of M_* have been artificially moved −0.05 dex for the unbound outflows measurements, and +0.05 dex for the expelled mass rate.
