The relation SFR − M _⋆  for the total sample. Filled circles (empty circles) illustrate galaxies for which the age of the young stellar population is found to be greater (lower than or equal to) than 0.3 Gyr by CIGALE. AGNs are represented by red stars. We overplot the semi-analytical Millennium simulations (cyan diamonds), analytical models of Buat et al. (2008) (dash-dotted yellow line) at z = 0.7 and Noeske et al. (2007a) (connected blue crosses) at z ~ 0.7 with observations of Elbaz et al. (2007) (solid black line, z = 0 and 1), Daddi et al. (2007) (solid black line z = 2), and Santini et al. (2009) at z ~ 0.7 (dashed green line).
