Abstract

Hydrodynamical simulations are used in combination with the Press-Schechter expression to simulate Sunyaev-Zel'dovich (SZ) galaxy cluster sky maps. These are used to gauge the ability of future SZ observations to provide information about the cosmological parameters H₀, Omega_M, and the gas fraction f_g in clusters. This work concentrates on prospects for AMI, the Arcminute MicroKelvin Imager, a new type of compact interferometric array currently proposed in Cambridge. The expectations are contrasted with those for X-ray missions, such as XMM, and the benefits of combining SZ and X-ray data are highlighted.
