Data on the comoving IR bolometric luminosity density from 8 to 1000 μm as a function of redshift for the IR-selected galaxy population, compared with our model prediction discussed in Sect. 3. The luminosity density here is expressed in solar luminosities per cubic Mpc. Line types are as in the previous figures. Blue filled squares are estimates of the bolometric IR emissivity based on the Herschel data by Gruppioni et al. (2013) and the cyan circles by Dunlop et al. (2017). Red filled square datapoints are from the analysis of the 24 μm luminosity functions by Rodighiero et al. (2010), green triangles are from Perez-Gonzalez et al. (2005), all expressed in terms of bolometric luminosity density (left ordinate axis). The filled green circles are from Vaccari et al. (2010) and Marchetti et al. (2016). The black dashed line corresponds to the Madau & Dickinson (2014) fit to the star-formation rate density versus redshift, scaled from M/yr to IR luminosity in L with the factor 1.7 × 10-10, as in Kennicutt (1998) for their adopted Salpeter’s IMF.
