Upper panel: evolution in the SMD of passive galaxies above 10¹⁰ M_⊙ (green symbols and shaded area). As for comparison, the SMD of all H < 27 galaxies integrated above the same mass limit is also plotted (shaded grey region). In both cases, the shaded regions represent the 1σ uncertainty. The results are compared to a number of literature works, as listed in the legend, for passive galaxies (open blue symbols) and for the entire population (open dark red symbols and dot dashed line). The literature estimates and their mass integration limits have been scaled to a Salpeter IMF, when needed. The dashed orange and dotted red lines indicate the SMD derived by integrating SFR density from Hopkins & Beacom (2006) and Madau & Dickinson (2014), respectively, assuming a constant recycle fraction of 28%. The solid blue line shows the prediction for the SMD in passive galaxies by Renzini (2016). Lower panel: ratio of the mass density of passive galaxies to the overall galaxy population above 10¹⁰ M_⊙ (solid green line and solid region). The passive fractions in terms of mass densities measured by Muzzin et al. (2013; triangles), Straatman et al. (2014; squares), Ilbert et al. (2013; 7-point stars), McLeod et al. (2021; pentagons), Mawatari et al. (2020; 5-point star), and predicted by Renzini (2016; solid line) are shown.
