Empowering Cluster Cosmology: Models, Simulations and Reality
Presented by Gus Evrard
University of Michigan, Ann Arbor

Abstract
As endpoints of cosmic structure formation that emerge in the era of dark energy domination, the population of clusters of galaxies offers insights into the nature of cosmology and gravity. Astronomers are well on their way to mapping the cosmography associated with clusters across the entire visible universe; sample sizes closing in on one million objects. The composition of dark matter and baryons in multiple phases within massive halos is being scrutinized across the electromagnetic spectrum and with increasingly sophisticated numerical simulations. In this talk, I will outline the phenomenological framework of cluster cosmology, emphasizing multi-wavelength population statistics and support from astrophysical simulations, then discuss some of the challenges associated with early 21st century reality.
