Fraction of SH mass with respect to the total mass within the virial radius of the halo presented as a function of halo mass. Similar to the ICL fraction in the same halo mass range (Contini et al. 2024c), there is no correlation observed in groups and clusters. However, there are indications of a decreasing fraction on smaller scales than loose groups, once the resolution of the simulations is taken into account. Our model predictions (red and blue lines) are compared with the extrapolated observed data by Ragusa et al. (2023) from the VEGAS survey (brown symbols) and the SH mass fraction reported by Deason et al. (2019) for the Milky Way (green symbol).
