Point Sources in the Context of Future Sz Surveys
We look at the impact of Infra-Red (IR) and radio point sources on upcoming large yield SunyaevZel’dovich (SZ) cluster surveys such as APEX, SPT and ACT. The IR and radio point source counts are based on observations by the the SCUBA and WMAP instruments respectively. We show that the contributions from IR source counts, when extrapolated from the SCUBA frequency of 350GHz to the operating freq...

Finding Clusters in SZ Surveys
We use simulated maps to investigate the ability of high resolution, low noise surveys of the CMB to create catalogues of Clusters of galaxies by detecting the characteristic signature imprinted by the Sunyaev Zeldovich effect. We compute the completeness of the catalogues in our simulations for several survey strategies, and evaluate the relative merit of some Fourier and wavelet based filteri...

The Selection Function of SZ Cluster Surveys
We study the nature of cluster selection in Sunyaev-Zel'dovich (SZ) surveys, focusing on single frequency observations and using Monte Carlo simulations incorporating instrumental effects, primary cosmic microwave background (CMB) anisotropies and extragalactic point sources. Clusters are extracted from simulated maps with an optimal, multi–scale matched filter. We introduce a general definitio...
