AbstractAST 99-80846. California Institute of Technology. PI: T.G. PhillipsAstronomical Studies with the Caltech Submillimeter ObservatoryThis award supports research, technological development, and student education at the Caltech Submillimeter Observatory (CSO). The CSO consists of a 10.4-meter-diameter, high surface precision antenna located at an altitude of nearly 14,000 feet, just below the summit of Mauna Kea on the island of Hawaii. The CSO's mission is to carry out spectroscopic and continuum observations of astronomical objects in the wavelength range 1mm-350mm; the opacity of the Earth's atmosphere to radiation at these wavelengths is the reason for the observatory's location at high altitude. The observatory was constructed with funds from the NSF during the period 1984-1987. The CSO is presently the only US facility capable of operations throughout the full submillimeter atmospheric window.Using new cameras and other enhanced instrumentation, the CSO is proposing in the next three years to carry out three key projects: (i) detection and study of the interstellar medium in distant and possibly primordial galaxies; (ii) pursuit of high-frequency Sunyaev-Zel'dovich measurements in a large enough galaxy cluster sample to make a meaningful independent measurement of the Hubble constant; and (iii) study of the very earliest stages of star formation in the dense interstellar medium

摘要AST 99-80846。 加州理工学院。 PI：T.G.菲利普斯与加州理工学院亚毫米天文台的天文研究该奖项支持加州理工学院亚毫米天文台 (CSO) 的研究、技术开发和学生教育。 CSO 由直径 10.4 米、高表面精度天线组成，位于海拔近 14,000 英尺、位于夏威夷岛莫纳克亚山山顶下方。 CSO的使命是对1mm-350mm波长范围内的天文物体进行光谱和连续观测； 地球大气层对这些波长辐射的不透明度是天文台位于高海拔的原因。 该天文台是在 1984 年至 1987 年间由 NSF 资助建造的。 CSO 是目前唯一能够在整个亚毫米大气窗口运行的美国设施。CSO 提议使用新相机和其他增强型仪器在未来三年内开展三个关键项目：(i) 探测和研究遥远星系和可能原始星系中的星际介质； (ii) 在足够大的星系团样本中追求高频 Sunyaev-Zel'dovich 测量，以便对哈勃常数进行有意义的独立测量； (iii) 研究致密星际介质中恒星形成的最早阶段
