COLIBRE simulations find kinematic galaxy morphology peaks in rotational support at stellar masses of 1-2 x 10^10 solar masses and correlates more with internal properties like gas richness than with host halo properties.
Star-forming galaxies show R_e,J ∝ (1+z)^(-0.92) and μ_J evolution with γ=3.07 while quiescent galaxies evolve faster (β=-1.34, γ=3.70) at fixed stellar mass, with evolution driven by luminosity and size changes.
