Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
X-RAY AND OPTICAL STUDY OF A SAMPLE OF RICH, REGULAR CLUSTERS
ABSTRACT
We propose to use ASCA to map the distribution of X-ray temperature, and the X-ray morphology for the 3 of the most regular clusters within the volume-limited ENACS (ESO Nearby Abell Cluster Survey) sample of rich clusters. This will complete an ASCA sample of the 5 most regular ENACS clusters for which we have high-quality radial velocity data. Combined studies of the structure and dynamics of IGM and galaxies and detailed comparisons with our simulations will provide further insight into the evolutionary history of clusters. Because of the well-understood properties of the sample, cosmological implications can be drawn from statistical measures of the sample.
