Collaborative Research: The CO Mapping Array Pathfinder

该计划的目标是为CO测绘阵列探路者（COMAP）实验调试偏振敏感无线电接收器和建立数字后端，并使用该设备在直径10米的射电望远镜上进行为期两年的观测。COMAP计划是天文学界为了解宇宙的起源和演化以及恒星和星系的形成所做的更大努力的一部分。更广泛的影响包括指导本科生和研究生在仪器仪表开发方面的研究训练。COMAP团队将通过公开讲座、网页和望远镜活动来传达他们的结果。学生和早期职业研究人员将在射频设计、技术开发和大型数据集分析方面接受各种尖端技术的培训。这项提案资助的人员将参加欧文斯谷射电天文台的教育和推广计划，将科学研究的兴奋带给包括印第安人在内的多元化社区。COMAP的目标是测量红移2.4 z2.8处的CO J=1-0跃迁和5.8 z6.7处的J=2-1跃迁的发射，探测CO的三维功率谱，它作为恒星形成的示踪剂。

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.
