Cosmic SFRD. The blue dots correspond to the averaged SFRD resulting from the two IRX calibrations, with the upper and lower limits of the blue-filled area corresponding to the calibration with and without stacking, respectively. The error bars on the blue dots are computed using the faint-end slope uncertainty of the SFR functions, α = −1.3 ± 0.1. In the top panel, SFRDs from other observational studies are added with colors depending on their estimator: UV (blueish), infrared (reddish), and radio (black). In the bottom panel, SFRDs measured from the four hydrodynamical simulations are added. In both subplots, we also add the contributions to the cosmic SFRD of different stellar-mass and SFR regimes (color-shaded areas).
