Description
Atlas Image mosaic of the galaxy cluster Abell 3558, also known as Shapley 8. This is a rich cluster, which has been the subject of study at a number of wavelengths. The cluster is dominated by a central giant cD galaxy (the brightest galaxy near the center of the 2MASS image), which, interestingly enough, also lies near the center of the larger Shapley concentration, or supercluster, of 25 clusters of galaxies, including Abell 3558. Dantas et al. (1997, ApJ, 485, 447) recently found that the cluster is actually composed of a collection of several groups of galaxies, suggesting that it is a dynamically complex, young cluster of galaxies.
