Predicted evolution of the cosmic stellar mass density ρ_∗ with redshift. The lines show the inferred mass density by extrapolating our stacked SFRs down to M_∗ = 3 × 10⁹ M_⊙ and out to z = 6 using the trend from Madau & Dickinson (2014) and integrating as a function of time. Stellar lifetimes are accounted for, and the mass of stellar remnants is included in ρ_∗ (see text). Colors are the same as in Fig. 13: the solid purple line shows the contribution of stacked sources with significant signal, the green line shows the contribution of galaxies in the regimes where we have probed the existence of the main sequence, and the orange line is the contribution of individually detected FIR sources. Shaded regions in the background show the corresponding 1σ statistical errors. We compare these results to the literature compilation of Madau & Dickinson (2014) shown as open triangles.
