Cosmic sSFR vs. z extrapolated beyond the observed limit at z = 3.6 with different options (see text). At z < 4, crosses are extracted from several galaxy surveys and are shown as a function of the considered log 10M in Noeske et al. (2007), Daddi et al. (2007), and Wuyts et al. (2011) and at z > 4 in Bouwens et al. (2012). Below z = 3.6, our data suggest that the sSFR are dominated by log 10M ~ 10.5−11.0 galaxies. At z > 4 the extrapolations agree with log 10M ~ 9.5, as evaluated by Bouwens et al. (2012).
