Composite cluster stellar mass functions show marginal M* evolution at high z and a factor of 2.5 growth in stellar mass fraction from z=0.8 to 0.2 after accounting for halo mass growth.
AGN emission from central galaxies hides galaxy clusters in SZ surveys; CARMA-based subtraction recovers high-SNR detections in ACT maps for three specific clusters.
Optical follow-up of 32 Planck SZ candidates yields photometric redshifts and richness estimates confirming 18 (7) as at least half as rich as expected at z>0.5 (z>0.8), highlighting Eddington bias and projection effects.
