Mass loading factor as a function of the dynamical mass. The continuous line represents an unweighted linear fit (in log) to the non-AGN LIRGs. The short- and long-dash discontinuous lines represent the predicted behaviour according to the models by Hopkins et al. (2012) () and Lagos et al. (2013), respectively. For the comparison with the models of Lagos et al. we consider M_stellar ≈ M_dyn. See text.
