Ultraviolet luminosity functions. The different panels correspond to different redshift ranges. Predictions of our model are compared to a set of observations: Arnouts et al. (2005): dark blue circles; Oesch et al. (2010): dark green up-triangles; Cucciati et al. (2012): blue circles; McLure et al. (2013): orange down-triangles; Oesch et al. (2013) yellow up-triangles; Alavi et al. (2014): green low-triangles; Parsa et al. (2016): dark green diamonds; Hagen et al. (2015): grey low-triangles; Bouwens et al. (2015) lightblue pentagons; Finkelstein et al. (2015): light green squares; Atek et al. (2015): light-green up-triangles; and Livermore et al. (2017): purple pentagons. In each panel f_ext indicates the fraction of the intrinsic UV emission of stars, which is attenuated by dust. The tick marks on the left side of each panel allow to us link the comoving density to the effective number of galaxies taken into account in the luminosity function.
