The goal of this project is to carry out a systematic study, from radio to gamma-ray wavelengths, of theprogenitors and explosion properties of short- and long-duration gamma-ray bursts (GRBs) -- the most extreme form of astronomical transient phenomena -- and to exploit their intense brightness to study the chemical enrichment of galaxies at unprecedented redshifts. The project will provide a comprehensive set of GRB and host galaxy observations to both determine the nature of GRB progenitors and to probe the high redshift universe. The results will be used to confront theoretical GRB progenitor models, and to uncover the evolution of galaxies and the intergalactic medium at high redshift.Broader impacts of the work include training of undergraduate and graduate students, and postdocs. The project will introduce the dynamic universe to middle- and high school students across the country, through a new program with the Harvard-Smithsonian MicroObservatory, a network of automated on-line telescopes. The program will enable students to design and execute their own GRB and supernova observations.

该项目的目标是从无线电到伽马射线波长，对短持续时间和长持续时间伽马射线爆发（伽马射线暴）-最极端形式的天文瞬态现象-的前身和爆炸特性进行系统研究，并利用其强烈亮度研究星系在前所未有的红移下的化学富集。该项目将提供一套全面的伽玛射线暴和宿主星系观测，以确定伽玛射线暴祖先的性质，并探测高红移宇宙。研究结果将用于对抗理论伽玛暴祖先模型，揭示高红移星系和星系际介质的演化。这项工作的更广泛影响包括本科生、研究生和博士后的培训。 该项目将通过一个与哈佛-史密森尼显微天文台（一个自动在线望远镜网络）合作的新项目，向全国各地的初中和高中学生介绍动态宇宙。该计划将使学生能够设计和执行自己的GRB和超新星观测。
