Contribution to the CIB per redshift slice, extracted from Béthermin et al. (2011). The black solid line is the CIB spectrum predicted by the model. The contribution to the CIB from 0 < z < 0.3, 0.3 < z < 1, 1 < z < 2 and z > 2 galaxies is given by the red short-dashed, green dot-dashed, blue three dot-dashed and purple long-dashed lines, respectively. Lower limits coming from the stacking analysis at 100 μm, 160 μm (Berta et al. 2010), 250 μm, 350 μm, 500 μm (Marsden et al. 2009), 850 μm (Greve et al. 2010) and 1.1 mm (Scott et al. 2010) are shown as black arrows. The black diamonds give the Matsuura et al. (2011) absolute measurements with AKARI. The black square the Lagache et al. (2000) absolute measurements with DIRBE/WHAM and the cyan line the Lagache et al. (2000) FIRAS measurement.
