Relation between the stellar sAM j_⋆ and for z = 1 TNG50 SFGs. The solid points with errorbars represent the median difference between the two as a function of the stellar angular momentum, where the error bars represent the standard deviation. Thus, the SFR-weighted sAM, , is higher by ≈ 0.25 dex (dotted line) compared to j_⋆ over a wide range of sAM from 50 to 2000 km s⁻¹ kpc. A second order polynomial fit is shown with the dot-dashed black line.
