Clusters of galaxies among ROSAT blank field sources
Abstract
We present here an efficient method for selecting high luminosity and massive high redshift clusters of galaxies, crucially important tools in cosmology. By selecting bright and extremely X-ray loud (high F(X)/F(V)) sources, we were able to identify 2 high redshift (z=0.45 and z=0.89) clusters so far and we have evidence for at least one more candidate at 0.4<z<1.1 out of a total of 16 selected sources.
