Upper panel: UV and IR SFRFs at different redshifts. Data points are plotted in cyan (UV) and red (IR), with best-fit curves shown as blue (UV) and red (IR). Lower panel: Product of volume density (Φ) and SFR in each redshift bin, which is integrated to obtain the SFRD. The UV (blue area) and the IR (red area) SFR density distributions are compared at different redshifts as a function of the SFR. Both curves are normalized so that the UV peak is at 1.
