In the early universe, massive galaxies grew rapidly through intense bursts of star formation, and then quenched (abruptly stopped forming stars at high rates). Principal Investigators Papovich and Marchesini will use the Second Florida Multi-Object Imaging Near-Infrared Grism Observational Spectrometer (FLAMINGOS2, F2) on the Gemini-South Telescope to conduct a census of these distant massive galaxies and study the underlying physical processes that transform the galaxies from star forming to quenched. The team will participate in Warrior-Scholar boot camps at Texas A&M University, which assist students as they transition from active military service to higher education. In addition, the team will mentor a summer student selected from the Tufts University Visiting and Early Research Scholars Experience Program. This program has a partnership with Historically Black Colleges.The team are using their custom built near infrared blue filter (centered at 2.0 micron) and red filter (centered at 2.3 micron) in order to be sensitive to the 4000 Angstrom/Balmer break for galaxies at redshifts 3 z 6. The team will conduct the 0.5 square degree F2 Extragalactic Near-IR K-Split Survey (FENIKS). The survey will image three deep legacy fields, the Cosmic Evolution Survey, the Great Observatories Origins Deep Survey – South, and the Ultra Deep Survey. The team will study the stellar populations and supermassive black holes in massive (log(M/Msun) 10.9) galaxies and determine when galaxies first begin to quench. The team will also identify and study hundreds of extreme galaxies with intense nebular emission, which are important in the context of galaxy formation and cosmic reionization.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在早期宇宙中，大质量星系通过强烈的星星形成爆发而迅速生长，然后熄灭（突然停止高速形成恒星）。 主要研究员帕波维奇和马切西尼将使用双子座南望远镜上的第二个佛罗里达多目标成像近红外光栅观测光谱仪（FLAMINGOS 2，F2）对这些遥远的大质量星系进行普查，并研究星系从星星形成到淬灭的潜在物理过程。该团队将参加德克萨斯A M大学的学者靴子营地，帮助学生从现役兵役过渡到高等教育。此外，该团队将指导从塔夫茨大学访问和早期研究学者体验计划中选出的暑期学生。该项目与Historically Black Colleges有合作关系。该团队正在使用他们定制的近红外蓝色滤光片（中心为2.0微米）和红色滤光片（中心为2.3微米），以便对红移为3 z 6的星系的4000埃/巴耳末突变敏感。该团队将进行0.5平方度F2河外近红外K分裂调查（FENIKS）。该调查将成像三个深遗产领域，宇宙演化调查，大天文台起源深调查-南方和超深调查。该小组将研究大质量（log（M/Msun）10.9）星系中的恒星种群和超大质量黑洞，并确定星系何时开始开始熄灭。该团队还将识别和研究数百个具有强烈星云发射的极端星系，这些星系在星系形成和宇宙再电离的背景下非常重要。该奖项反映了NSF的法定使命，并通过使用该基金会的智力评估被认为值得支持优点和更广泛的影响审查标准。
