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.

首席研究员 (PI) 鲁德尼克 (Rudnick) 和威尔逊 (Wilson) 正在研究遥远的大质量星团中的恒星形成是如何被抑制（淬灭）的。该团队将把新的分析技术应用于丰富早期环境中的双子座星系观测 (GOGREEN) 调查的图像。通过校正地球大气层的模糊效应，新图像将足够清晰，可以看到星系是从内到外、从外到内还是从任何地方熄灭同时，以及这如何取决于星系的位置（靠近星团中心或在郊区），PI Wilson 将在河滨的加州聋人学校举办天文学研讨会，强调听觉以外的感官，例如“嗅觉”。 PI Rudnick 将继续他为期一年的高中研究计划，其中包括在堪萨斯大学举行的小型小型研讨会。该团队将使用有限分辨率反卷积 (Firedec) 代码可将亚弧秒地面图像的分辨率大幅提高约 2.5 倍，而无需任何形态学先验。他们将使用生成的高分辨率多色 GOGREEN 图像来识别哪些区域。每个星系的颜色都与猝灭一致，从而确定模式（从内到外、从外到内或同时到处），以及这如何取决于进入星系团后的环境和时间。该团队还将测量该模式。确定从恒星形成到被动转变的星系的恒星质量剖面，以确定星系内恒星质量的分布及其形态如何随着恒星形成的淬灭而变化。所有数据产品都将公开。该奖项反映了 NSF 的法定使命。通过使用基金会的智力优点和更广泛的影响审查标准进行评估，并被认为值得支持。
