Total stellar-to-halo fraction. Left: total stellar-to-halo fractions M_⋆/M_vir as a function of the stellar mass M_⋆ obtained from our 3D fits. The error bars from our data are 95% confidence intervals, and the open circles show the sample of Genzel et al. (2020). The shaded (blue contours) histogram shows the location of SFGs in the TNG simulations for z = 1 centrals, while the gray contours show the satellites. The colored lines show the Behroozi et al. (2019) relation inferred from semi-empirical modeling at redshifts z = 0.5, 1.0, 1.5, respectively. Right: total stellar-to-halo fractions M_⋆/M_vir as a function of GM_vir/j_⋆σ_⋆ (Eq. (7)) for the galaxies in our sample. The inset histogram shows that the sample has (≡⟨Q_⋆⟩, Eq. (6)), see text.
