摘要：

Chandra observations of the galaxy cluster A3667 are analyzed. The X-ray data strongly suggest that there is a giant cloud of cold plasma separated by a sharp boundary (cold front) from the hotter intergalactic medium. Analysis of the cold-front properties allows one to study a number of physical processes in the intergalactic medium: large-scale gas motions, transport processes, and magnetic-field structure and strength.
