Halo scale radius-density relation at z = 1. Left: ρ_s − r_s scaling relation for the galaxies shown in Fig. 7. The error bars are 95% confidence intervals (2σ). For comparison, the anticorrelation of Kormendy & Freeman (2004), Spano et al. (2008) and Di Paolo et al. (2019) are shown. Right: DM surface density (Σ_s ≡ ρ_s r_s) as a function of galaxy mass. The anticorrelation in the left panel implies a constant DM surface density. The gray band represents the range of surface densities from Burkert (2015) for dwarfs. The constant densities of Kormendy & Freeman (2004) and Donato et al. (2009) are shown as the dotted, dot-dashed lines, respectively.
