Notes. (1) Though all three simulations are available until z = 0, we use only z ≥ 0.5 snapshots because the contribution of SMGs at low-redshift is negligible. (2) Central subhalo is the most massive subhalo of any group, (3) Stellar mass of the subhalo, (4) Size of spherical aperture placed on subhalo center for measurements [in physical kpc].
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
