Observational analysis of COSMOS galaxy groups shows quiescent fraction builds steadily from z~1.5-2 with faster growth in richer groups, first RS ridgeline galaxies by z~2, a possible early overdensity at z=3.4, and no significant evolution in RS slope or scatter.

Euclid Q1 data shows the passive-density and morphology-density relations persist from z=0.25 to z=1, with local density increasing the quenched and early-type fractions at fixed stellar mass for galaxies below 10^10.8 solar masses.

COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction
Observational analysis of COSMOS galaxy groups shows quiescent fraction builds steadily from z~1.5-2 with faster growth in richer groups, first RS ridgeline galaxies by z~2, a possible early overdensity at z=3.4, and no significant evolution in RS slope or scatter.

Euclid Quick Data Release (Q1): The evolution of the passive-density and morphology-density relations between $z=0.25$ and $z=1$
Euclid Q1 data shows the passive-density and morphology-density relations persist from z=0.25 to z=1, with local density increasing the quenched and early-type fractions at fixed stellar mass for galaxies below 10^10.8 solar masses.
