[58.04] Measurements of the SZE in a Complete Sample of Nearby Clusters of Galaxies

S.T. Myers, B.S. Mason (University of Pennsylvania)

Matter density and gravitational potential fluctuations in the Early and Late Universe imprint characteristic signatures on the Cosmic Microwave Background that can in principle be decoded through high-precision radio wavelength observations. Recent results from programs that put this into practice will be presented. The focus of the talk will be the Penn-OVRO Sunyaev-Zeldovich Survey, which targets a complete X-ray selected sample of nearby massive clusters of galaxies and has yielded a robust measurement of the baryonic mass in the intercluster medium, as well as a determination of the Hubble Constant. The future of these programs in the context of the Cosmic Background Imager project will also be discussed.
