SAGE: A Submillimeter Grating Spectrometer for Exploring Distant Galaxies

ast -0096881高灵敏度光谱仪，专为观测河外天体在亚毫米（350、450和610微米）波段的点源光谱而设计，瞬时带宽为6.7 GHz。将被设计、工程、建造、校准和应用于获取数据：研究早期宇宙中的恒星形成，测量光学模糊的遥远星系的红移，利用光谱学研究超发光星系（最初由IRAS发现）的来源，并研究原始星系。这种新仪器是一种背景有限中分辨率光谱仪，称为SAGE（亚毫米波阵列光栅探测器）。＊＊＊

AST-0096881Stacey, Gordon J.A highly sensitive spectrometer designed specifically to observe Extragalactic objects for point source spectroscopy in the submillimeter (350, 450, and 610 micrometer) bands with an instantaneous bandwidth of 6.7 GHz. will be designed, engineered, built, calibrated and applied to acquire data to: Investigate star formation in the early universe, measure redshifts of optically obscured distant galaxies, investigate the sources in Ultraluminous galaxies (originally discovered by IRAS) using spectroscopy, and investigate proto-galaxies. This new instrument is a background limited moderate resolution spectrometer called SAGE for Submillimeter Array Grating Explorer. ***
