A Bolometric Receiver for Sunyaev-Zel'dovich measurements with the APEX Telescope

AST-0138348Lee， AdrianA毫米波辐射热测量接收机将为位于德国波恩的马克斯普朗克射电天文研究所（MPIfR）的12米直径阿塔卡马探路者实验（APEX）望远镜建造。该接收机是一个300元的辐射热计接收机，用于150和217 GHz的观测。辐射热计将是喇叭耦合的蜘蛛网装置，带有超导晶体管边缘传感器（TES），每个传感器都使用配置为1024个元件的SQUID电流表读出。该接收器将用于通过热Sunyaev-Zel'dovich （SZ）效应在毫米波长下发现和研究星系团。光学和x射线测量记录的数据，当与该接收器记录的数据相关联时，承诺1。揭示星系的形成历史；2 .通过测量暗能量的状态方程来探测暗能量的本质；测量宇宙学参数，包括质量能量密度和哈勃常数。＊＊＊

AST-0138348Lee, AdrianA millimeter wave bolometric receiver will be built for the 12-meter diameter Atacama Pathfinder Experiment (APEX) telescope in transition with Max Planck Institute for Radioastronomy (MPIfR) in Bonn, Germany. This receiver is a 300-element bolometric receiver for observations at 150 and 217 GHz. The bolometers will be horn-coupled, spider-web devices with superconducting transistor-edge sensors (TES) each using SQUID ammeter readout configured for 1024 elements. This receiver will be used to discover and study galaxy clusters via the thermal Sunyaev-Zel'dovich (SZ) effect at millimeter wavelengths. Data recorded with optical and x-ray measurements, when correlated with data recorded by this receiver promise to 1. reveal the formation history of galaxies, 2. Probe the nature of dark energy by measuring its equation of state, and 3. measure cosmological parameters including the mass energy density and the Hubble constant. ***
