Proposal ID: AST-0239370Institution: University of Colorado BoulderPI: Glenn, JasonDr. Jason Glenn will use his CAREER award at the University of Colorado, Boulder to develop new millimeter-wave instrumentation in order to measure the redshifts of submillimeter galaxies. These galaxies, discovered by their submillimeter or millimeter-wave dust emission, are found at high redshifts and are very luminous. With redshifts determined from the rotational lines of CO, it will be possible to measure the luminosity function and cosmic formation history of high star formation rate, dust-obscured galaxies. Dr. Glenn will use mature bolometer technology and an innovative waveguide-coupled diffraction grating to create a unique broadband spectrometer called Z-Spec. This new spectroscopic capability will make it possible to capitalize on ongoing and imminent submillimeter galaxy surveys. This award will enable Dr. Glenn to turn a laboratory demonstration facility into an instrument for ground-based submillimeter telescopes.As well as training graduate and undergraduate students in millimeter-wave instrumentation, Dr. Glenn will conduct an education and outreach program designed to expose high school students and the public to astronomy research through a set of classroom visits and lectures. Electronic presentations on our rapidly evolving understanding of the early universe will be developed for presentation at the University of Colorado's Fiske Planetarium and Boulder/Denver-area high schools. These presentations will be written and given with substantial participation by undergraduate students in the university's astronomy education track. Dr. Glenn will also work on developing active learning in the classroom and in the planetarium through the use of interactive teaching combined to provide real-time feedback on comprehension.

提案ID：AST-0239370机构：科罗拉多大学博尔德PI：Glenn，JasonDr.杰森·格伦将利用他在博尔德市科罗拉多大学获得的职业生涯奖，开发新的毫米波仪器，以测量亚毫米星系的红移。 这些星系是通过它们的亚毫米波或毫米波尘埃辐射发现的，它们的红移很高，而且非常明亮。由CO的转动谱线确定的红移，将有可能测量高星星形成率、尘埃遮蔽星系的光度函数和宇宙形成历史。Glenn博士将使用成熟的测辐射热计技术和创新的波导耦合衍射光栅来创建一个独特的宽带光谱仪，称为Z-Spec。这种新的光谱能力将使正在进行和即将进行的亚毫米星系调查成为可能。该奖项将使Glenn博士能够将一个实验室演示设施变成地基亚毫米波望远镜的仪器。除了培训研究生和本科生使用毫米波仪器外，Glenn博士还将开展一项教育和推广计划，旨在通过一系列课堂访问和讲座，使高中生和公众接触天文学研究。关于我们对早期宇宙迅速发展的理解的电子演示将在科罗拉多大学的菲斯克天文馆和博尔德/丹佛地区的高中进行演示。这些演讲将由大学天文学教育轨道的本科生撰写并大量参与。Glenn博士还将致力于在课堂和天文馆中开展主动学习，通过使用交互式教学结合起来，提供实时的理解反馈。
