Chandra Observation of the Multiple Merger Cluster Abell 521

We present the Chandra analysis of the rich galaxy cluster Abell 521 (z=0.247). The high resolution of the Chandra observation has allowed us to refine the original merging scenario proposed for A521, and to reveal new features in its X-ray emission. A521 has strongly substructured ICM density and temperature maps. Its X-ray diffuse emission is elongated… CONTINUE READING
