Oral Presentation Clusters and Cosmology I


Bradford Benson (Fermilab, University of Chicago)


I will give an overview of Sunyaev-Zel'dovich (SZ) cluster surveys, the resultant cosmological constraints, and projected future results. Since the first SZ-discovered cluster in 2008, there are now over 1500 SZ-selected clusters reported in the literature. Ongoing surveys from AdvACT and SPT-3G promise to deliver samples with several thousand additional clusters in the next few years, with the future CMB-S4 experiment expected to find over 100,000 clusters. These data sets promise to deliver unique samples of massive clusters at z > 1, including proto-clusters detected at z > 4 from their mm-wave emission The resultant cosmological constraints from the cluster number density will require an understanding of the cluster selection and mass calibration, which will rely on multi-wavelength data from overlapping X-ray and optical surveys that will enable additional cosmological studies. I will summarize these upcoming results, challenges, and projected cosmological constraints.
