Scientific paper

We propose to obtain 10 ksec ACIS-I images for 10 medium-bright clusters of galaxies selected in the 160 square degree ROSAT PSPC survey. These observations will complete a flux-limited (f>1.4e-13 erg/s/cm^2) and redshift-limited (z>0.4) subsample of this survey. The goal of the proposed observations is to obtain accurate X-ray luminosities, excluding substructures and emission from the cooling cores. The accurate Lx measurement will allow to estimate temperatures and baryon masses using L-T and M_g-T correlations recently calibrated for z~0.5 clusters. We therefore will significantly improve statistics in the measurements of the evolution of the temperature and baryon mass functions of distant clusters and will be able to obtain more precise cosmological constraints.
