XMM Clusters of galaxies in COSMOS field

We reach a depth for a total cluster flux in the 0.5-2keV band of 3x10^-15^ergs/cm^2^/s, having one of the widest XMM-Newton contiguous raster surveys, covering an area of 2.1deg^2^. Cluster candidates are identified through a wavelet detection of extended X-ray emission.

Verification of the cluster candidates is done based on a galaxy concentration analysis in redshift slices of thickness 0.1-0.2 in redshift, using the multiband photometric catalog of the COSMOS field and restricting the search to z<1.3 and i_AB_<25. We identify 72 clusters and derive their properties based on the X-ray cluster scaling relations. A statistical description of the survey in terms of the cumulative log(N>S)-logS distribution compares well with previous results, although yielding a somewhat higher number of clusters at similar fluxes.
