Studying how these extreme structures grow and evolve over cosmic time is therefore of great importance. Although clusters are relatively well-s tudied in the local universe\, studies of galaxy clusters at high-redshif ts are more sparse owing to the difficulty in identifying large numbers o f clusters and in getting suitable follow-up data on them. This period ab ove z = 1 is a crucial period in cluster evolution as they stop forming s tars and transition into the settled behemoths they are today. The Massiv e and Distant Clusters of WISE Survey (MaDCoWS) uses infrared WISE data t o find the most significant galaxy overdensities at z ~ 1. Follow-up Suny aev-Zel'dovich (SZ) observations have provided ICM confirmation of more t han twenty MaDCoWS clusters—including MOO J1142+1527\, the most massive c luster detected by any method above z = 1.15—while follow-up Spitzer/IRAC observations have allowed us to reliably measure their stellar mass. I w ill be showing comparisons of the stellar mass fractions of these high-re dshift\, infrared-selected MaDCoWS clusters to SZ-selected clusters from the South Pole Telescope (SPT) survey at similar redshift and to previous studies at low-redshift. I will also discuss recent work studying the ev olution of the cluster luminosity function (LF) as a function of redshift \, and what this tells us about cluster and galaxy evolution in these ext reme environments.\n\n\nThis seminar will be held exclusively on Zoom (95 5 5209 1021).
