Galaxy cluster
- Cluster stellar mass growth is mostly established by redshift 0.8
- AGN jet lobe growth matches self-similar scaling
-
Deep Chandra observations of a relaxed z = 1.16 galaxy cluster Chandra X-ray observations of SPT-CL J2215-3537 resolve the cool core of this z = 1.16 relaxed galaxy cluster, establishing a high-redshift benchmark for cluster evolution studies.
