CAREER: Millimeter-Wave Instrumentation Development for Measuring the Redshifts of Submillimeter Galaxies

提案ID：AST-0239370机构：科罗拉多大学博尔德PI：Glenn，JasonDr.杰森·格伦将利用他在科罗拉多大学博尔德分校获得的职业奖项，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或毫米波尘埃发射发现的，红移很大，非常明亮。根据CO的旋转线确定的红移，将有可能测量高恒星形成率、尘埃遮挡的星系的光度函数和宇宙形成历史。格伦博士将使用成熟的测辐射热计技术和一种创新的波导耦合衍射光栅来创造一种独特的宽带光谱仪，称为Z-Spec。这一新的光谱能力将使其有可能利用正在进行和即将进行的亚毫米星系调查。这一奖项将使格伦博士能够将实验室演示设施改造成地面亚毫米望远镜的仪器。除了对研究生和本科生进行毫米波仪器培训外，格伦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，让高中生和公众接触天文学研究。科罗拉多大学的菲斯克天文馆和博尔德/丹佛地区的高中将开发关于我们对早期宇宙快速演变的理解的电子演示文稿。这些报告将由大学天文学教育领域的本科生大量参与撰写和发表。格伦博士还将致力于在课堂和天文馆发展主动学习，方法是结合使用互动教学，提供实时的理解反馈。

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.
