Drivers of the evolution in our scaling relations. The top panels compare how the local TFR and FR (blue curves) would evolve (orange curves) if the only changes are the z evolution of the Hubble parameter and the density contrast, against our high-z data (green markers) and best fits (pink curves). The results imply an evolution of $f_{\mathrm{V}}{f}_{\mathrm{M}}^{-1/3}$ and $f_{\mathrm{j}}{f}_{\mathrm{M}}^{-2/3}$. The bottom panels show f_M and f_j at z = 0 (blue) and z = 0.9 (pink) as a function of M_*, as implied by our best-fitting relations after assuming f_V = 1.3 ± 0.1. The dashed grey line and bands in the bottom right panel show f_j at z = 0.9 under the assumption that f_M does not evolve with redshift. In all the panels, bands correspond to 1 σ confidence bands around the mean relations. Note that the vertical axis span in the bottom panels is the same, highlighting the stronger mass dependency of f_M over f_j.
