Chandra Weighs Most Massive Galaxy Cluster in Distant Universe (22 Dec 2014)
A newly discovered galaxy cluster, XDCP J0044.0-2033 nicknamed
the Gioiello or Jewel Cluster, is the
most massive cluster ever detected with an age of 800 million years or less.
Using data from Chandra, Tozzi et al. (2015, ApJ, in
