Why do SZ Blind Survey?


Find SZ selected sample of clusters
Followup in X-ray etc to do "single cluster" studies:
Hubble constant, Gas mass fraction
Joe Mohr yesterday

Use number of clusters as function of redshift (and mass) to:
Confirm LCDM paradigm! (non Gaussianity?)
Further constrain cosmological parameters (w):
Need a lot of clusters and hard systematics!

Large redshift reach of SZ, and near-constant limiting mass advantages for both.
