Evolution of star formation density with redshift as constrained by the linear CIB model. The ± 1σ and ± 2σ confidence region around the median realisation is shown in yellow and blue, respectively. Measurements of obscured star formation density from Gruppioni et al. (2013), Magnelli et al. (2013), and Marchetti et al. (2015), which were used to fit the CIB model, have been added along with the measurements from Bourne et al. (2017) in the upper panel. The Gaussian form of the ρSFR for the IR obscured star formation rate density used by Koprowski et al. (2017) has been plotted as the black dashed line in the upper panel with a corresponding UV part in the lower panel. Unobscured star formation rate density derived from UV from Cucciati et al. (2012), Bouwens et al. (2012), and Reddy & Steidel (2009) are also shown in the lower panel.
