Abstract:
Recent technological advances allow for the construction of instruments which can survey the sky for clusters of galaxies via the redshift-independent Sunyaev-Zel'dovich effect, and therefore can test theoretical models of cluster evolution and constrain the model parameters. Our work quantifies these expectations by using cluster gas simulations and the Press-Schechter expression to produce sky maps, and then simulating the telescope observation of these in detail. Key constraints on the matter density, the gas evolution in clusters and the power spectrum can be obtained from the study of clusters selected from a blank field SZ survey. AMI, the Arcminute MicroKelvin Imager, an interferometric array described by Jones and Saunders in this volume, has the performance needed.
