论文摘要

我们提出了一个4195的目录,由4195个光学确认的Sunyaev-Zel'Dovich(SZ)选定的星系簇在13,211 v $^2 $^2 $中被检测到的Atacama Cosmology Telescope(ACT)的Sky in 13,211度$^2 $。通过将多频匹配的过滤器应用于从2008 - 2018年获得的ACT观测值中构建的98和150 GHz地图,选择群集候选物,并使用深层,广阔的光学光学调查确认。簇跨越红移范围0.04 <z <1.91(中值z = 0.52)。目录包含222 Z> 1个簇,总共868个系统是新发现。假设通过X射线观察校准了SZ信号与质量缩放关系,则该样品的完整性质量限制为M500C> 3.8 x 10 $^{14} $ msun,以z = 0.5进行评估,用于在信号 - 噪声比率> 5中检测到的群集,该群集在2.4''的词汇尺度上被映射> 5。这项调查与深度光学弱透镜调查有很大的重叠,该调查用于校准SZ信号质量尺度关系,例如Dark Energy Survey(4566度$^2 $),超级Suprime-Cam Subaru战略计划(469度$^2 $)和kilo Leger survey(825 $^2 $^2 $^2 $)。我们重点介绍了样本中一些值得注意的对象,包括潜在的预测系统;具有强烈镜头特征的簇;有活跃的中央星系或星形形成的簇;以及可能与物理相关的多个群集的系统。群集目录将是对未来宇宙学分析的有用资源,并研究了过去10个GYR中大型簇中群内培养基和星系的演变。

We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise > 4 in 13,211 deg$^2$ of sky surveyed by the Atacama Cosmology Telescope (ACT). Cluster candidates were selected by applying a multi-frequency matched filter to 98 and 150 GHz maps constructed from ACT observations obtained from 2008-2018, and confirmed using deep, wide-area optical surveys. The clusters span the redshift range 0.04 < z < 1.91 (median z = 0.52). The catalog contains 222 z > 1 clusters, and a total of 868 systems are new discoveries. Assuming an SZ-signal vs. mass scaling relation calibrated from X-ray observations, the sample has a 90% completeness mass limit of M500c > 3.8 x 10$^{14}$ MSun, evaluated at z = 0.5, for clusters detected at signal-to-noise ratio > 5 in maps filtered at an angular scale of 2.4'. The survey has a large overlap with deep optical weak-lensing surveys that are being used to calibrate the SZ-signal mass-scaling relation, such as the Dark Energy Survey (4566 deg$^2$), the Hyper Suprime-Cam Subaru Strategic Program (469 deg$^2$), and the Kilo Degree Survey (825 deg$^2$). We highlight some noteworthy objects in the sample, including potentially projected systems; clusters with strong lensing features; clusters with active central galaxies or star formation; and systems of multiple clusters that may be physically associated. The cluster catalog will be a useful resource for future cosmological analyses, and studying the evolution of the intracluster medium and galaxies in massive clusters over the past 10 Gyr.
