Astronomical Resarch with the Owens Valley Millmeter Array

摘要AST 99-81546。加州理工学院。PI：A.I SargentOwens山谷毫米计阵列的天文研究该奖项支持欧文斯谷毫米仪阵列的研究、技术开发和学生教育。该阵列由六个直径10.4米的天线组成，位于加利福尼亚州毕晓普附近。欧文斯河谷毫米波阵列的任务是对频率范围为30-245 GHz的天文天体进行光谱和连续谱观测。天文台是用国家科学基金会和私人资金建造的。欧文斯山谷毫米计阵列目前是美国在毫米波长波段进行干涉观测的两个设施之一(另一个是BIMA阵列，也由美国国家科学基金会资助)。在接下来的三年里，欧文斯山谷毫米计阵列计划执行下列科学计划：(I)搜索高红移星系的CO和连续谱发射。(Ii)星系核中致密气体的亚反正秒分辨率绘图。(Iii)形成星团的分子云核的分子线和连续谱马赛克。(Iv)在0.4“尺度上对T-Tauri和HerBig Ae恒星进行多线测量。(V)用HST观测近红外原行星盘。计划的技术发展包括：(I)实施双偏振接收器。(Ii)完成新的眼镜蛇宽带相关器。(Iii)安装新的前端冷却的水蒸气监测仪。

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.
