A Deep Chandra X-ray Observation of El Gordo Conference Paper uri icon


  • Abstract We present new results on ACT-CL J0102-4915 (" El Gordo") based on a deep Chandra observation. We present a temperature map on sub-arcminute scales that shows significant variations from a low of 5 keV near the location of the brightest cluster galaxy (BCG) to a high of 25 keV. The cold core shows evidence for a cold front, an interface across which the temperature decreases while the density rises, providing further evidence for a major merger in El Gordo. We also examine the locations of merger shocks as traced by …
