Astronomical Studies with the Caltech Submillimeter Observatory

加州理工学院亚毫米波天文台（CSO）运行着美国唯一的亚毫米波望远镜。它具有连续光谱和光谱观测的卓越灵敏度，角分辨率在30到8弧秒之间，可以进行创新项目，为天文学的许多领域提供关键的新信息，包括太阳系、银河系、以及银河系外的现象。这笔拨款将支持一个多方面的科学研究和技术发展计划，重点是CSO的10.4米直径望远镜。该望远镜位于夏威夷莫纳克亚山海拔4100米的地方，那里的大气非常干燥，非常适合观察短至320微米的波长。在拨款期间，新的接收器应可用于波长短于800微米的常规观测。一半的观测时间可供一般天文团体使用。

The California Institute of Technology Submillimeter Observatory (CSO) operates the only U.S. based submillimeter wavelength telescope. With excellent sensitivity for both continuum and spectroscopic observations and with angular resolutions between 30 and 8 seconds of arc, innovative projects can be undertaken to provide critical new information in many fields of astronomy, including studies of the Solar System, our Galaxy, and extragalactic phenomena. This grant will support a multifaceted scientific research and technology development program focussed on the 10.4 meter diameter telescope of the CSO. The telescope is sited at an altitude of 4100 meters on Mauna Kea, Hawaii, where the atmosphere is very dry and ideal for observations at wavelengths as short as 320 microns. During the grant period, new receivers should become available for routine observations at wavelengths shorter than 800 microns. One half of the observing time is available for use by the general astronomy community.
