AST 96-15025. California Institute of Technology. PI: T. G. Phillips Astronomical Studies with the Caltech Submillimeter Observatory This award supports research, technological development and student education at the Caltech Submillimeter Observatory (CSO). The Observatory consists of a precision 10.4m antenna enclosed in a dome located near the summit of Mauna Kea, Hawaii. The CSO's mission is to carry out spectroscopic and continuum observations of astronomical objects in the wavelength range 1mm-350 mm; the opacity of the Earth's atmosphere to radiation at these wavelengths is the reason for the observatory's location at an altitude of nearly 4,300m. The observatory was constructed with funds from the National Science Foundation (NSF) during the period 1984-1987. The CSO is presently the only US facility capable of operations throughout the full submillimeter atmospheric window. Over the next three years, the CSO will focus on three major goals: 1. The detection and study of the interstellar medium in distant and possibly primeval galaxies. 2. The study of star formation in the interstellar medium, particularly the very early stages of the process. 3. The extension of previously-successful Sunyaev-Zel'dovich measurements to a wide range of galaxy clusters to allow estimates of the Hubble constant.

AST 96-15025。加州理工学院。PI：T. G. 菲利普斯 加州理工大学亚毫米波天文台（Caltech Submillimeter Observatory） 该奖项支持加州理工学院亚毫米波天文台（CSO）的研究，技术开发和学生教育。 该天文台由一个精密的10.4 m天线组成，该天线封闭在位于夏威夷莫纳克亚山山顶附近的圆顶中。天文台的使命是对波长范围在1毫米至350毫米的天体进行光谱和连续观测;地球大气层对这些波长的辐射不透明是天文台设在近4，300米高度的原因。该观测站是在1984-1987年期间由国家科学基金会（NSF）提供资金建造的。CSO是目前美国唯一能够在整个亚毫米大气窗口运行的设施。 在未来三年内，CSO将专注于三大目标： 1. 对遥远的和可能是原始星系中的星际介质的探测和研究。 2. 星际学对星际介质中星星形成的研究，尤其是该过程的早期阶段 3.将先前成功的Sunyaev-Zel'dovich测量扩展到广泛的星系团，以估计哈勃常数。
