X-Ray Observations of Cluster Mergers: Cluster Morphologies and Their Implications

Abstract

X-ray observations have played a key role in the study of substructure and merging in galaxy clusters. I review the evidence for cluster substructure and mergers obtained from X-ray observations with satellites that operated before Chandra and XMM. Different techniques to study cluster mergers via X-ray imaging and spectral data are discussed with an emphasis on the quantitative analysis of cluster morphologies. I discuss the implications of measurements of cluster morphologies for cosmology and the origin of radio halos.
