Abstract
This talk presents a summary of the most recent results from microwave and millimeter-wave surveys of the Sunyaev-Zeldovich Effect (SZE) in massive clusters of galaxies. The SZE is caused by Compton scattering of low-energy CMB photons off high-temperature ionized gas in cluster atmospheres, and is a direct measurement of the baryon content of the intracluster medium. New results from the Chicago-BIMA SZE survey of Carlstrom et al., the Penn-OVRO SZE program of Mason et al., and the Caltech-CBI SZE project of Padin et al. are discussed, along with prospects for future imaging and interferometric studies of clusters to pin down the astrophysical properties of cluster baryons and dark matter as well as possible constraints on cosmological parameters.
