CLF extracted from the MARIGOLD simulations at z = 5 in three halo mass bins. The contributions from central and satellite [C II] emitters are indicated in different colours. The scale of the y-axis changes in the different panels. Quantitative information about the CLF is provided in Table 2. The top two panels refer to the high-resolution simulation, and the bottom panel is obtained from the low-resolution simulation, which contains more massive haloes.
