SFR and M_⋆ for the full sample (black circles), the stacked sample (gray squares with error bars), the three sources in udf-10 (yellow circles), and the individual Si II* halos (red crosses), compared to those of galaxies z = 2.1–3.9 in the DR2 catalog (gray dots). Due to the large 1σ uncertainties in SFR and M_⋆ (Bacon et al. 2023), error bars are shown only for the stacked sample" for clarity and conciseness. The full sample lies along the relation for the galaxies at z = 2.1–3.9 in the same catalog, which suggests that our sample is not biased toward starburst galaxies.
