Principal Investigators (PIs) Rudnick and Wilson are investigating how star formation is suppressed (quenched) in galaxies residing in distant massive clusters. The team will apply new analysis techniques to images from The Gemini Observations of Galaxies in Rich Early ENvironments (GOGREEN) Survey. By correcting for the blurring effect of the earth’s atmosphere the new images will be sharp enough to see if galaxies quench from the inside-out, outside-in, or everywhere simultaneously, and how this depends on the location of the galaxy (near a cluster center or in the outskirts). PI Wilson will develop and host astronomy workshops at the California School for the Deaf, Riverside, emphasizing senses other than hearing e.g., “Smelling the Universe” and “Touching the Universe.” PI Rudnick will continue his year-long high school research program that includes a capstone mini-symposium at the University of Kansas.The team will use the Finite-Resolution Deconvolution (Firedec) code to robustly increase the resolution of their sub-arcsecond ground-based images by a factor of approximately 2.5 without requiring any morphological priors. They will use the resulting high resolution multi-color GOGREEN images to identify which regions of each galaxy have colors consistent with quenching, thus determining the mode (inside-out, outside-in, or everywhere simultaneously), and how this depends on environment and time since entering a cluster. The team will also measure the stellar mass profiles of galaxies identified as transitioning from star forming to passive to determine how the distribution of stellar mass within galaxies, and hence their morphology, changes as star formation quenches. All data products will be made publicly available.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.

首席研究人员（PIS）Rudnick和Wilson正在研究居住在遥远大型群集中的星系中如何抑制恒星形成（淬火）。该团队将对在丰富的早期环境（Gogreen）调查中的双子座观察结果的图像中应用新的分析技术。通过纠正地球大气的模糊效果，新图像将足够锋利，以查看星系是否从内而外，外部或任何地方淬火，以及这如何取决于星系的位置（群集中心附近或郊区）。皮·威尔逊（Pi Wilson）将在加利福尼亚聋人学校（Riverside）的加利福尼亚学校开发和举办天文学讲习班，强调除了听到“闻到宇宙闻到宇宙”和“触及宇宙”以外的感觉。 Pi Rudnick将继续他的为期一年的高中研究计划，其中包括堪萨斯大学的Capstone Mini-Symposium。该团队将使用有限的分辨率反卷积（FIREDEC）代码来稳健地增加其亚弧形地面图像的分辨率，而不需要任何人的道德priors。他们将使用所得的高分辨率多色gogreen图像来确定每个星系的哪些区域具有与淬火一致的颜色，从而确定模式（内外，外部或其他地方），以及这如何取决于自进入集群以来的环境和时间。该团队还将测量被确定为从恒星形成到被动过渡的星系的恒星质量曲线，以确定星系中恒星质量的分布如何，因此它们的形态随着恒星形成而变化。所有数据产品都将公开可用。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估被认为是宝贵的支持。
