Evolution of the star-forming (blue) and quiescent (orange) galaxy components of the galaxy stellar mass function in nine bins of redshift (0.2 < z < 4.5). Uncertainty envelopes correspond to 1 and 2σ limits. For comparison, we show other literature studies in COSMOS from Ilbert et al. (2013) and Davidzon et al. (2017) that adopt similar selections and methodologies. For reference, the total SMF is shown in each bin (solid gray) and the 0.2 < z < 0.5 total SMF is repeated in each panel (purple dotted). Mass incomplete measurements as defined by the channel 1 limiting magnitude are not shown, with the mass limits corresponding to the K_s limiting magnitude shown by orange arrows. Upper limits for empty bins are shown by the horizontal gray line and arrow.
