This is a program to study, via optical integral field unit spectroscopy, the astrophysics of submillimeter galaxies (SMGs), which are thought to be young galaxies in the process of formation. The main goals are 1) To reveal the astrophysics of a statistically useful sample of several hundred high-redshift SMGs, and their counterparts detected using Spitzer Space Telescope; 2) To understand the place of SMGs as signposts to active regions of the distant Universe, and their role in defining the stars in disks and bulges/spheroids in galaxies today. This research will lead to a better understanding of galaxy formation in the early universe and the nature of galaxies today. Broader impacts include research training for undergraduates, interaction with local K-12 educators, and providing tours of local K-12 students to the Palomar and Owens Valley observatories.

这是一个通过光学积分场单位光谱学研究亚毫米星系(SMGs)的天体物理学的计划，SMG被认为是正在形成过程中的年轻星系。主要目标是1)揭示统计上有用的数百个高红移SMG的样本的天体物理学，以及使用斯皮策太空望远镜探测到的对应样本；2)了解SMG作为遥远宇宙活动区的路标的位置，以及它们在确定今天星系中的盘状和凸起/球体中的恒星方面的作用。这项研究将有助于更好地了解早期宇宙的星系形成和今天星系的性质。更广泛的影响包括对本科生的研究培训，与当地K-12教育工作者的互动，以及为当地K-12学生提供参观帕洛马和欧文斯山谷天文台的机会。
