Contribution of HST+near-IR dark galaxies to ρ_SFR(z): the derivation from this work (ALMA selection) in two redshift intervals (i.e. z = 2.2–4.0 and 4.0–6.0) is shown via the magenta filled area and the black stars, and is compared to the derivation by Wang et al. (2019) from H-dropout selection (blue open squares and line), by Yamaguchi et al. (2019) from ASAGAO (purple filled area), and by Williams et al. (2019) from the ALMA selection (green diamond). The red boxes with black circles and the violet filled pentagons (the same as in Fig. 16) represent the obscured and unobscured SFRD from this work and from Bouwens et al. (2015), respectively.
