Top: Median sSFR of SF galaxies as a function of redshift in the field (dotted), groups (dashed), and clusters (solid). Bottom: The logarithmic ratio of sSFR for group to field galaxies (dashed), and for cluster to field galaxies (solid). At fixed masses, the decrease
level is very similar for cluster galaxies or group galaxies in different redshift ranges, and the reduction offset is seen <0.4 dex for clusters and <0.2 dex for groups. That is, the
decrease of sSFRs for the group to field galaxies and for the cluster to field ones is independent of redshift, implying an universal slow quenching mechanism acting in the dense environments since z ~ 1.1.

First results on the cluster galaxy population from the Subaru Hyper Suprime-Cam survey. I. The role of group or cluster environment in star formation quenching from z = 0.2 to 1.1

$Top: The quiescent fraction from the radial (solid lines) and density (dashed lines) contribution. Three stellar mass ranges are plotted: 10.1<log10(Ms/Me)<10.5 (green), 10.5<log10(Ms/Me)<10.9 (blue), and log10(Ms/Me)>10.9 (gold). Bottom: The excess of the quiescent fraction (Δ) from the radial (solid lines) and density (dashed lines) contribution relative to the fraction from the field. For less massive galaxies, the Δ in groups or clusters has a radial gradient, implying that the location of the less massive galaxies in their parent halo has an additional effect on their star formation quenching.$
