The Bayesian Galaxy Cluster Finder and its Application to Large Surveys

One of the main purposes of Large Surveys is the study of galaxy clusters. However, it is not an easy task to compile a complete sample. In this talk, I will present a new technique for detecting galaxy clusters called the Bayesian Cluster Finder (BCF) which is able to determine the position, redshift and richness of clusters in any survey. I will introduce the simulations that we performed to test the algorithm through realistic mock galaxy catalogs and discuss their completeness and purity in terms of mass and redshift of the cluster. In addition, I will show the results of testing this algorithm in the CFHTLS Archive Research Survey (CARS) and the Deep Lens Survey (DLS).
