Three-dimensional Thermodynamic Structures of the Intracluster Medium across Edges in the X-Ray Surface Brightness of Massive, Bright, Dynamically Active Galaxy Clusters
Chandra X-ray images around the cold fronts in A3667 (top left) and A2319 (top right), respectively, and around the shock fronts in A520 (bottom left) and A2146 (bottom right), respectively. The overlaid, dashed white sectors denote the directions along each sector analyzed and the edge positions associated with the fronts. The middle and dashed white lines correspond to the positions of the bump-like substructures. The yellow bar in each panel shows the spatial scale of the images.
