Evolution of the star formation density (upper panel) and effective bias as a function of redshift (lower panel), as constrained by the linear part of the power spectra. In both panels, the median realization of the model is represented with a red line, the ± 1σ confidence region with a dark orange area, and the ± 2σ region with a light orange area. In the upper panel, we added the measurements of obscured star formation from infrared Magnelli et al. 2011, squares; Rodighiero et al. 2010, asterisks; Cucciati et al. 2012, diamonds; Gruppioni et al. 2013, crosses, and unobscured star formation from uncorrected UV (Bouwens et al. 2007, triangles; Reddy & Steidel 2009, circles). In the lower panel, we also plot the evolution of the dark matter halo bias for dark matter halo mass of 1011M⊙ (dashed line), 1012M⊙ (dot-dashed line), and 1013M⊙ (three-dots-dashed line).
