Cosmology with Sunyaev-Zel'dovich cluster counts

Jochen Weller

University College London

I will discuss the possibility of using SZ galaxy cluster counts to constrain cosmological models. I will pay particular attention to uncertainties and scatter in the mass - observable relation, how weak lensing imaging surveys can be used in calibrating this relation and how we can obtain prior information from numerical simulations.
