Collaborative Research: The CO Mapping Array Pathfinder

该计划的目标是调试一个偏振敏感无线电接收器，并为CO映射阵列探路器(COMAP)实验建立一个数字后端，以及使用该设备在10米直径的射电望远镜上进行为期两年的观测。COMAP计划是天文学团体为了解宇宙的起源和演化以及恒星和星系的形成而做出的更大努力的一部分。这项工作的更广泛影响包括对本科生的指导和对研究生在仪器开发方面的研究培训。COMAP团队将通过公开讲座、网页和望远镜活动来交流他们的结果。学生和职业生涯初期的研究人员将接受射频设计、技术开发和大数据集分析方面的各种尖端技术培训。这项提案资助的人员将参加欧文斯山谷无线电天文台的一项教育和外展计划，将科学研究的兴奋带给包括美国原住民在内的多元化社区。COMAP的目标是测量红移为2.4 z 2.8的CO J=1-0跃迁和红移为5.8 z 6.7的J=2-1跃迁的发射，探测作为恒星形成示踪剂的CO的3D功率谱。

The objective of this program is to commission a polarization-sensitive radio receiver and build a digital backend for the CO Mapping Array Pathfinder (COMAP) experiment, as well as observe for two years using this equipment on a 10m-diameter radio telescope. The COMAP program is part of a much larger effort by the astronomical community to understand the origin and evolution of the universe and the formation of stars and galaxies. Broader impacts of the work include mentoring of undergraduates and research training of graduate students in instrumentation development. The COMAP team will communicate their results via public lectures, web pages, and activities at the telescope. Students and early-career researchers will be trained in a variety of cutting edge techniques in radio frequency design, technology development and analysis of large data sets. Personnel funded by this proposal will participate in an education and outreach program at the Owens Valley Radio Observatory, bringing the excitement of scientific research to a diverse community that includes a Native American population. COMAP aims to measure emission from both the CO J=1-0 transition at redshifts 2.4 z 2.8 and the J=2-1 transition at 5.8 z 6.7, probing the 3D power spectrum of CO, which acts as a tracer for star formation.
