Abstract (from CDS):

We present measurements of the stellar mass fractions (f*) for a sample of high-redshift (0.93 <= z <= 1.32) infrared-selected galaxy clusters from the Massive and Distant Clusters of WISE Survey (MaDCoWS) and compare them to the stellar mass fractions of Sunyaev-Zel'dovich (SZ) effect-selected clusters in a similar mass and redshift range from the South Pole Telescope (SPT)-SZ Survey. We do not find a significant difference in mean f* between the two selection methods; though, we do find an unexpectedly large range in f* for the SZ-selected clusters. In addition, we measure the luminosity function of the MaDCoWS clusters and find m* =19.41±0.07, similar to other studies of clusters at or near our redshift range. Finally, we present SZ detections and masses for seven MaDCoWS clusters and new spectroscopic redshifts for five MaDCoWS clusters. One of these new clusters, MOO J1521+0452 at z = 1.31, is the most distant MaDCoWS cluster confirmed to date.
