论文摘要
星系簇随红移的函数的特性可以用作重要的宇宙学工具。我们提出了来自Sunyaev-Zeldovich效应（SZE）的后续观测计划中的初步结果，该效应在高红移星系簇中检测到了在巨大和遥远的Wise Survey（Madcows）中的红外波长下检测到的。使用每个集群3-4小时的典型源源整合时间，绿色银行望远镜上的Mustang2能够测量16个目标中14个SZE降低的强烈检测和统计学意义的质量。在其余两个上，获得了SZE信号的较弱（3.7 Sigma）检测，并获得了质量上的强上限。在本文中，我们介绍了每个目标的质量和压力谱，并概述用于恢复这些数量的数据分析。在具有很强检测的簇中，三个显示出明显的压力曲线，而从野马2数据中，另外五个显示了核心中断的迹象。但是，在集群核心之外，我们无法检测到大量的不对称性。最后，有迹象表明，疯子使用的光学丰富度与Sze贡献的质量之间的关系可能比以前的研究中所指出的显着。
The properties of galaxy clusters as a function of redshift can be utilized as an important cosmological tool. We present initial results from a program of follow-up observations of the Sunyaev-Zeldovich effect (SZE) in high redshift galaxy clusters detected at infrared wavelengths in the Massive and Distant Clusters of WISE Survey (MaDCoWS). Using typical on-source integration times of 3-4 hours per cluster, MUSTANG2 on the Green Bank Telescope was able to measure strong detections of SZE decrements and statistically significant masses on 14 out of 16 targets. On the remaining two, weaker (3.7 sigma) detections of the SZE signal and strong upper limits on the masses were obtained. In this paper we present masses and pressure profiles of each target and outline the data analysis used to recover these quantities. Of the clusters with strong detections, three show significantly flatter pressure profiles while, from the MUSTANG2 data, five others show signs of disruption at their cores. However, outside of the cores of the clusters, we were unable to detect significant amounts of asymmetry. Finally, there are indications that the relationship between optical richness used by MaDCoWS and SZE-inferred mass may be significantly flatter than indicated in previous studies.
