  • We present the [CII]158μm line luminosity functions (LFs) at z ∼ 4−6 using the ALMA observations of 118 sources, which are selected to have UV luminosity M_(1500A) 10⁹ L_⊙) compared to z∼0. This excess is consistent with a potential population of [C II]-bright UV-faint sources that are largely excluded from the ALPINE target selection. To further constrain such sources, in a companion analysis, Loiacono et al. (2020) estimate the [C II] LF based on serendipitous [C II] sources in the ALPINE… CONTINUE READING
