Abstract

In this work we show how well can the cosmological parameters be constrained using galaxy cluster data. We also show how in the process of fitting the model which attempts to describe the data it is possible to get some information about the cluster scaling relations T − M and Lx −T. Among other conclusions we found that only low density universes (Ω ≈ 0.3 with or without Λ) are compatible with recent data sets. These constraints will be improved with future SZ data.
