SPT-CL J0205–5829: A<i>z</i>= 1.32 EVOLVED MASSIVE GALAXY CLUSTER IN THE SOUTH POLE TELESCOPE SUNYAEV-ZEL'DOVICH EFFECT SURVEY

SPT-CL J0205–5829: A<i>z</i>= 1.32 EVOLVED MASSIVE GALAXY CLUSTER IN THE SOUTH POLE TELESCOPE SUNYAEV-ZEL'DOVICH EFFECT SURVEY

The galaxy cluster SPT-CL J0205−5829 currently has the highest spectroscopically confirmed redshift, z = 1.322, in the South Pole Telescope Sunyaev–Zel'dovich (SPT-SZ) survey. XMM-Newton observations measure a core-excluded temperature of TX = 8.7+1.0−0.8 keV producing a mass estimate that is consistent with the Sunyaev–Zel'dovich-derived mass. The combined SZ and X-ray …
