Strong constraints on cosmology from galaxy clusters
  In this work we show how galaxy clusters can be used to discriminate among different cosmological models. We have used available X-ray & optical cluster data to constrain the cosmological parameters as well as the cluster scaling relations, T-M and L-T. We also show the power of future SZE data to constrain even more these parameters.
