Passive fractions for all galaxies (left panel), central galaxies (middle panel), and satellites (right panels). Symbols correspond to observational measurements. In particular: squares correspond to estimates from Davies et al. (2019) based on the GAMA survey, and adopt a log(sSFR) threshold of −10.5 yr⁻¹ to identify passive fractions. Filled and empty circles correspond to measurements based on SDSS DR8 and are obtained assuming a threshold of −11 yr⁻¹ and −10.6 yr⁻¹, respectively. Solid lines correspond to predictions from different models, as indicated in the legend, assuming a log(sSFR) threshold of −11.0 yr⁻¹ to select passive galaxies. The grey regions show the minimum-maximum fractions obtained when considering predictions from the GAEA2023 model from 125 independent boxes, each of 100 Mpc h⁻¹ on a side. The dashed line shows predictions from the GAEA2020X model corresponding to a log(sSFR) threshold of −10.6 yr⁻¹, as adopted in Xie et al. (2020).
