Description

The recent combination of deep Sunyaev Zel'dovich (SZ) surveys with pointed X-ray follow-up has enabled the study of the intracluster medium across most of cosmic time. In particular, within the South Pole Telescope (SPT) collaboration, we have been utilizing Chandra and XMM-Newton follow-up of SPT-selected clusters to study the evolution of the dynamical state, the cooling/heating balance, and the metal enrichment of the intracluster medium over the past 10 Gyr. I will briefly summarize these results, before describing the numerous synergies of SPT-3G and eRosita, and previewing how these combined observatories will further unravel the complex history of the intracluster medium.
