Galaxy clusters are the next best thing for precision cosmology probes after the Cosmic Microwave Background. With the recent dramatic increase in sensitivity and resolution of sub-mm wavelength observations, we will soon begin to measure galaxy cluster peculiar velocities via the Sunyaev-Zel'dovich effect. However, detailed modeling of point sources, CMB contamination and velocity/temperature substructure within the cluster itself is required to acquire useful measurements with sufficient precision for cosmology. My poster will focus on how simulations will help us resolve these issues. This is work in progress supported in part by a NASA Graduate Student Research fellowship.
