X-ray structure of clusters of galaxies with ROSAT.
Abstract
Recent ROSAT observations show (1) the relaxed clusters like Coma and Abell 2256 have significant sub-clustering due to on-going mergers, (2) the existence of filamentary X-ray structure in the central regions of the cooling flow clusters, and (3) the dominance of dark matter and the lowest metal abundance in the gas in a small group of galaxies, NGC 2300. These results from ROSAT are reviewed.
