Properties of simulated galaxies with Mstar > 108 M⊙ at z = 6, including galaxies that do not host MBHs. From top to bottom: star formation rate averaged over 10 Myrs in black, and over 100 Myrs in gray; mass-weighted stellar age, and mass-weighted stellar metallicity, where solar metallicity is assumed to be 0.02, a dust mass within twice the effective radius. Reff is defined as the half-mass projected radius in the plane orthogonal to the stellar angular momentum, computed as the (2D) radius such that 50% of the mass is within that radius. The violet line in the top panel shows the fit from Speagle et al. (2014).
