Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
THE LAST FIVE HIGH REDSHIFT EMSS CLUSTERS
ABSTRACT
There are 23 Einstein Medium Sensitivity Survey clusters with z > 0.3. All but 4 have ROSAT HRI images and all but 6 have ASCA spectra. Of these 6, 1 is near NGC4151 whose scattered light precludes observations with ASCA. We propose to obtain the spectra of the last 5 feasible clusters. Our particular interest is to determine cluster temperature evolution in order to constrain cosmological parameters. However, there are many other uses for a complete sample of clusters with temperatures all measured with the same instrument.
