Cosmological Constraints from Sunyaev-Zeldovich Effect and X-ray data for 37 Galaxy ClustersWe present a sample of 37 clusters of galaxies (0.14<=z<=0.89) for which we have Sunyaev-Zeldovich Effect data and Chandra X-ray imaging and spectroscopy. We use a Markov chain Monte Carlo technique to determine the spatial properties and surface brightness of the X-ray emitting gas, the X-ray temperature and abundance, and the SZE decrement for each cluster. From these observables, we infer each cluster's total mass, gas mass fraction, and angular diameter distance. The sample properties are used to constrain the Hubble parameter and Omega Matter, and scaling relations between integrated SZE flux and cluster mass and temperature are constructed. We also investigate the cosmological constraints that could be obtained if the X-ray/SZE sample were extended to a redshift of z approximately 2.
