This award is for continuing support of research at the millimeter wave interferometer, operated by the California Institute of Technology in Owens Valley, California. The Principle Investigator, one of the world leaders in millimeter wave astronomy and radio interferometry, directs one of the most creative and productive groups of astronomers in the world. These workers have not only pioneered in the application of millimeter wave technology to important astronomical problems, but have also been instrumental in developing the technology itself. Objects to be investigated under this award range from our own solar system to the most distant galaxies. The first global measurement of Martian winds is expected, using absorption features of carbon monoxide. The high resolution of the three element array (soon to be expanded to six elements or more) will permit detailed mapping of circumstellar structure associated with young stellar objects - possibly planetary systems in the making. The great sensitivity of this instrument will allow the extension of cosmological studies of the Hubble expansion, now frequently conducted with the 21 cm radiation of neutral hydrogen, to the use of the millimeter wavelength lines of carbon monoxide. This will broaden the base of galaxies for which high accuracy red-shifts may be obtained.

这个奖项是为了继续支持毫米研究 波干涉仪，由加州研究所操作， 加州欧文斯谷的技术。 原则 他是世界毫米波天文学的领导者之一 和无线电干涉测量法，指导了一个最有创造性的， 世界上最多产的天文学家群体。 这些工人 不仅开创了毫米波技术的应用， 重要的天文学问题，但也有工具， 在发展技术本身。 该奖项下要调查的对象包括我们自己的 从太阳系到最遥远的星系 第一次全球 利用吸收特性， 一氧化碳 三元阵列的高分辨率 (soon扩展到六个元素或更多）将允许详细 与年轻恒星有关的星周结构测绘 可能是正在形成中的行星系统。 伟大 该仪器的灵敏度将允许扩展 哈勃膨胀的宇宙学研究，现在经常 用中性氢的21厘米辐射进行， 一氧化碳的毫米波谱线。 这将 扩大了星系的基础，高精度的红移可能 获得。
