This project studies the growth of massive galaxies in the first few billion years after the Big Bang. The target galaxies are magnified by "gravitational lensing," the bending of light around intervening galaxies, which allows them to be detected more easily and studied in greater detail than other galaxies at similar distance. The primary data come from the Atacama Large Millimeter/submillimeter Array (ALMA). With these and other data, the team will determine how these galaxies form stars so rapidly and shut down their formation so quickly, look for evidence of black hole growth in the galaxies, determine the number of such galaxies in the Universe to see how they affect the overall history of cosmic star formation, and test the modern cosmological paradigm by exploring their lensing in great detail. This award will support the teaching of astronomy through examples from this research to fifth grade classes in Illinois, hands-on radio astronomy technology experiences for high school students in Arizona, and training of undergraduate and graduate students in advanced techniques of radio astronomy and interferometry.The project will pursue several goals using gravitationally lensed galaxies discovered by the South Pole Telescope: (1) determine the triggering mechanisms for the most intense star formation events in the high redshift Universe, (2) study the regulation and termination of star formation by observing gas dynamics and outflows, (3) study the assembly of massive elliptical galaxies by determining stellar masses, star formation rates, and gas content in such galaxies at very high redshift, (4) explore the coevolution of black hole accretion and stellar mass assembly in these objects, (5) measure metal enrichment with far-infrared atomic lines, (6) determine the space density of these extreme starbursts and connect them to state of the art galaxy formation simulations, and (7) identify substructure in the halos lensing these galaxies to test the predictions of current cosmology models. These goals are largely achievable based on the data already promised in ALMA cycles 3 and 4 using the advanced interferometric analysis tools that have been built up over the past several years. The team incorporates both observers and theorists to ensure that the lessons derived from these high-resolution views of the early Universe can be compared against and fed back into state-of-the-art galaxy formation simulations.

该项目研究了大爆炸后的头几十亿年，大规模星系的增长。 目标星系通过“重力透镜”放大，即在中间星系周围的光线弯曲，这使得它们比其他类似距离的星系更容易地检测到它们更详细地进行研究。 主要数据来自Atacama大毫米/亚毫米阵列（ALMA）。 使用这些数据和其他数据，团队将确定这些星系如何如此迅速地形成恒星并如此迅速地关闭它们的形成，寻找星系中黑洞生长的证据，确定宇宙中此类星系的数量，以了解它们如何影响它们宇宙之星形成的整体历史，并通过详细探索其镜头来测试现代宇宙学范式。 该奖项将通过从这项研究到伊利诺伊州的五年级课程，亚利桑那州的高中生的动手射电天文技术经验以及对射电射线天文学和干涉仪的高级技巧的本科生和研究生培训来支持天文学的教学。该项目将使用南极望远镜发现的重力镜头星系实现多个目标：（1）确定高红移宇宙中最激烈的恒星形成事件的触发机制，（2）研究通过观察恒星形成的调节和终止气体动力学和流出，（3）通过确定恒星质量，恒星形成速率和此类星系中的气体含量在非常高的红移时研究大规模椭圆星系的组装，（4）探索黑洞积聚和恒星质量组装的共同进化这些对象，（5）用远红外原子线测量金属富集，（6）确定这些极端星爆的空间密度，并将它们连接到最先进的星系形成模拟的状态，（7）识别在光环镜头中的子结构星系测试当前宇宙学模型的预测。 这些目标在很大程度上是可以基于在过去几年中建立的先进的干涉分析工具，基于ALMA周期3和4中已承诺的数据。 该团队都将观察者和理论家融合在一起，以确保可以将早期宇宙的这些高分辨率观点获得的课程与最先进的银河形成模拟进行比较。
