Top panel: Relation between stellar mass and parent halo virial mass for all galaxies selected at z ≳ 3.1 and z ≲ 5.3 (trends are similar when considering galaxies in smaller redshift ranges). Gray and cyan contours show the regions enclosing (from thicker to thinner lines) 30, 60, and 90% of the quiescent and star forming galaxies, respectively. Bottom panel: same as above, but including an estimate of the observational uncertainty (0.25 dex) in the galaxy stellar mass.
