We present first results from a galaxy population study in the highest redshift galaxy clusters identified in the 2500 deg$^2$ South Pole Telescope Sunyaev Zel'dovich effect (SPT-SZ) survey. The cluster selection is to first order independent of galaxy properties, making the SPT-SZ sample particularly well suited for cluster galaxy population studies. We carry out a 4-band imaging campaign with the {\it Hubble} and {\it Spitzer} Space Telescopes of the five $z\gtrsim 1.4$, S/N$_{SZE}>$5 clusters, that are among the rarest most massive clusters known at this redshift. All five show clear overdensities of red galaxies whose colors agree with the initial cluster redshift estimates. The highest redshift cluster in this sample, SPT-CLJ0459-4947 at $z\sim1.72$, is the most distant $M_{500}>10^{14}~M_{\odot}$ ICM-selected cluster discovered thus far, and is one of only three known clusters in this mass range at $z\gtrsim 1.7$, regardless of selection. Based on UVJ-like photometric classification of quiescent and star-forming galaxies, the passive fraction in the cluster central regions ($r/r_{500}<0.7$) is higher than in the field at the same redshift, with corresponding environmental quenching efficiencies typically in the range $\sim0.5-0.8$ for stellar masses $\log(M/M_{\odot})>10.85$. We have explored the impact of emission from star formation on the selection of this sample, concluding that all five clusters studied here would still have been detected with S/N$_{SZE}>$5, even if they had the same passive fraction as measured in the field. Our results thus point towards an efficient suppression of star formation in massive galaxies in the central regions of the most massive clusters, occurring already earlier than $z\sim1.5$.

Caught in the act: gas and stellar velocity dispersions in a fast quenching compact star-forming galaxy at z~1.7
我们介绍了GDN-8231的Y和H波段的Mask-I MOSFIRE光谱,GDN-8231是一个大质量、致密的恒星形成星系(SFG),红移为$z\sim1.7$。它的光谱揭示了H $_α$和[NII]发射线以及强的巴耳末吸收线。H $_α$和斯皮策MIPS 24 $μ$ m通量都很弱,因此表明SFR $\lesssim5-10$ M $_{\odot}$ yr $^{-1}$的恒星形成率很低。再加上从吸收线测量到的$\sim700$ Myr相对年轻的年龄,这为遥远的星系在快速关闭其恒星形成过程中被捕获提供了第一个直接证据。这样的淬灭使得GDN-8231成为一个紧凑的,静止的星系,类似于我们样本中的其他3个星系,通过$z\sim1.5$。此外,GDN-8231的颜色分布显示出更蓝的中心,与最近模拟的由内而外淬灭早期阶段的预测一致。它的气体视线速度色散$σ^{\rm{gas}}_{\!_{\rm LOS}}=127\pm32$ km s $^{-1}$比它的恒星$σ^{\star}_{\!_{\rm LOS}}=215\pm35$ km s $^{-1}$小近40%。星系的高分辨率流体模拟解释了这种明显较冷的气体运动学的$\sim1.5$的一个因素与旋转盘被认为是在不同的倾角和/或集中的恒星形成区域。一个明确的预测是,它们紧凑、静止的后代保留了一些来自恒星形成祖先的残余旋转。
