SPT-SZ是目前通过Sunyaev-Zel‘dovich(SZ)效应探测星系团的最强大的仪器。SPT-SZ焦平面由700多个由频域Squid多路复用器在三个不同通带(90 GHz、150 GHz和220 GHz)上观测的背景受限TES蜘蛛网测辐射热计组成。与10米南极望远镜一起,SPT-SZ在1度视场内实现了极高的极小分辨率分辨率,是第一个通过SZ效应发现新星系团的仪器。我们将讨论SPT-SZ的设计和部署,介绍前两个季节的初步结果,并概述未来的调查计划。
The SPT‐SZ is, currently, the most powerful instrument for detecting galaxy clusters through the Sunyaev‐Zel’dovich (SZ) effect. The SPT‐SZ focal plane consists of over 700 background limited TES spiderweb bolometers observing in three different pass bands (90 GHz, 150 GHz, and 220 GHz) readout by a frequency domain SQUID multiplexer. Together with the 10‐m South Pole Telescope, SPT‐SZ has realized exceptional sensitivity at arcminute resolution over a one degree field of view and is the first instrument to discover new galaxy clusters through the SZ effect. We will discuss the SPT‐SZ design and deployment, present initial results from the first two seasons, and outline future survey plans.
