Cold (left column), warm (central column), and hot (right column) gas mass versus M_star (top row) and SFR (bottom row) for galaxies at redshift z = 5.25, 6.14, 8.09, 10.00, 13.01, and 16.01, with simulation fits (dashed magenta lines) reported in Appendix F (Table F.1). Different gas phases probe different M_star and SFR regimes with little redshift evolution, but a large environment and feedback-driven scatter.
