Abstract
Clusters of galaxies detected in X-rays are ideal probes for the study of the large scale structure in the Universe. Based on the ROSAT All-Sky Survey we have conducted a large redshift survey as an ESO key programme to identify the X-ray brightest clusters found in the southern hemisphere. We present first results from the bright part of the survey comprising 460 identified clusters for an X-ray flux limit of 3.10(-12) erg s(-1) cm(-2). We show results for the X-ray luminosity function and discuss the assessment of the large-scale structure be means of the duster distribution power spectrum on a scale of 400h(-1) Mpc.
