CAREER: Enriching the Universe -- Investigating Nucleosynthesis and Galaxy Formation in the First Few Billion Years

职业生涯：丰富宇宙--研究最初几十亿年的核合成和星系形成。加州大学圣克鲁斯分校(UCSC)的杰森·普罗查斯卡将开展一项研究阻尼型Ly-a(DLA)系统的项目。此外，PI将对银河系厚盘中的化学丰度进行调查，对银河系中不同的化学耗竭进行分析，对伽马射线暴余辉进行光谱分析，并对少量高红移DLA系统进行丰度分析。这些项目将使普罗查斯卡博士能够建立一个全面的计划，在宇宙的最初几个回转期间研究核合成和星系形成。普罗查斯卡还将开展一项旨在促进高中探究性学习的科学教育计划。该项目的背景将是天文光谱，这将使他和他的同事使用的研究工具与他的教育努力相结合。该计划将有两个主要活动：1)在圣克鲁斯的几个高中课堂上进行探究性学习；2)在加州大学洛杉矶分校校园举行探究性学习教师座谈会

CAREER: Enriching the Universe -- Investigating Nucleosynthesis and Galaxy Formation in the First Few Billion Years ABSTRACTAST 0548180PI: Jason ProchaskaDr. Jason Prochaska at the University of California, Santa Cruz (UCSC) will undertake a program that involves investigations of damped Ly-a (DLA) systems. Additionally the PI will undertake a survey of chemical abundances in the Galactic thick disk, an analysis of the differential chemical depletion in the Milky Way, spectroscopy of gamma-ray burst afterglows, and abundance analyses of a modest sample of high redshift DLA systems. These projects will allow Dr. Prochaska to establish a comprehensive program for studying nucleosynthesis and galaxy formation during the first few Gyr of the universe.Dr. Prochaska will also undertake a science education program designed to promote inquiry-based learning in high schools. The context for the program will be astronomical spectra, which provides for an integration of the research tool he and his colleagues use with his educational efforts. The program will have two main activities: 1) inquiry-based learning in several Santa Cruz high school classrooms; and 2) teacher symposia in inquiry learning held on UCSC campus
