摘要AST 99-81546。 加州理工学院。 主要研究者：A.I Sargent与欧文斯谷毫米阵列的天文研究该奖项支持欧文斯谷毫米阵列的研究、技术开发和学生教育。 该阵列由位于加州毕晓普附近的六个直径为10.4米的天线组成。 天文台欧文斯谷毫米阵列的使命是在30-245千兆赫频率范围内对天文物体进行光谱和连续观测。 该观测站是由NSF和私人来源提供资金建造的。 欧文斯谷毫米阵列是目前美国从事毫米波段干涉观测的两个设施之一（另一个是比马阵列，也由NSF资助）。 在未来三年中，欧文斯谷毫米阵列计划开展以下科学计划：（i）探测高红移星系的CO和连续辐射。(ii)星系核致密气体的亚弧秒分辨率成图。(iii)成团分子云核的分子线和连续镶嵌。(iv)Tauri T和Herbig Ae星的0.4”尺度多线巡天。(v)用哈勃望远镜在近红外线观测原行星盘的调查。(ii)完成新型COBRA宽带相关器的集成。(iii)安装新的带有冷却前端的水蒸气监测器。

AbstractAST 99-81546. California Institute of Technology. PI: A.I SargentAstronomical Research with the Owens Valley Millimeter ArrayThis award supports research, technological development, and student education at the Owens Valley Millimeter Array. The Array consists of a six 10.4-meter-diameter antennas located near Bishop, California. The mission of the Owens Valley Millimeter Array of the is to carry out spectroscopic and continuum observations of astronomical objects in the frequency range 30-245 GHz. The observatory was constructed with funds from the NSF and from private sources. The Owens Valley Millimeter Array is presently one of two US facilities engaged in interferometric observations in the millimeter wavelength band (the other being the BIMA array, also funded by NSF). Over the next three years, the Owens Valley Millimeter Array plans to carry out the following scientific programs: (i) Searches for CO and continuum emission from high redshift galaxies.(ii) Sub-arcsecond resolution mapping of dense gas in galactic nuclei.(iii) Molecular line and continuum mosaics of cluster-forming molecular cloud cores.(iv) Multi-line surveys of T Tauri and Herbig Ae stars on 0.4" scales.(v) A survey of protoplanetary disks observed in the near infrared with HST.Planned technological developments include:(i) Implementation of dual polarization receivers.(ii) Completing the integration of the new COBRA broadband correlator.(iii) Installing new water vapor monitors with cooled frontends.
