SHMR (f − Mh, left), stellar mass-velocity scaling law (M − Vgal, middle), and the relation between galaxy velocity and halo velocity (Vgal − Vh, right) for the population of late types (blue) and massive early types (red). Top-middle and top-right panels: the characteristic velocity of galaxies Vgal is the velocity along the flat parts of HI rotation curves for late types (Vflat, Lelli et al. 2016b) and the velocity dispersion of stars within 1 kpc for early types (σ⋆, 1 kpc, Brodie et al. 2014). Bottom-middle and bottom-right panels: we substitute the observed Vgal with the circular velocity evaluated at the same radius (2Re) for both galaxy types. In all panels, we show power-law fits to the data of late types (blue dashed lines) and early types (red dotted lines).
