Collaborative Research: Discriminating Between Galactic Feedback Models with Next Generation Observations

星系中的恒星是由低温气体形成的，但恒星的形成和演化过程会使气体重新加热或被吹走。这种关于星系生长和演化的恒星反馈是理解星系如何在宇宙时间内生长的重要组成部分。该项目将在更大的宇宙学模拟中使用他们自己的恒星反馈模型。他们将产生数千个模拟星系，可以与观测到的星系进行比较，以更好地了解宇宙学中反馈的影响。该项目还将为佛罗里达州服务不足学区的中学生建立一个实地考察项目。学生们将参观当地的圣达菲天文馆。该项目将利用佛罗里达大学大学预科教育和教学中心来评估该计划的影响。该项目将把现有的明确恒星反馈模型（走私）纳入现有的AREPO宇宙模拟代码中。走私模型气体冷却，恒星形成，和恒星反馈。AREPO是图解宇宙学模拟的基础。该项目将从这些模拟中自动生成数千个星系，然后与观测结果进行比较。这个项目的大部分更广泛的影响将在佛罗里达大学进行。该项目将为佛罗里达州服务不足学区的中学生建立一个实地考察项目。学生们将参观当地的圣达菲天文馆。该项目将利用佛罗里达大学大学预科教育和教学中心来评估该计划的影响。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Stars form in galaxies from cool gas, but the act of star formation and the evolution of those stars can reheat the gas or blow it away. This stellar feedback on the growth and evolution of galaxies is an important part of understanding how galaxies grow over cosmological time. The project will use their own model for stellar feedback within larger cosmology simulations. They will produce thousands of simulated galaxies that can be compared with observed galaxies to better understand the influences of feedback in cosmology. The project will also establish a field trip program for middle school students in underserved school districts in Florida. The students will visit the local Santa Fe planetarium. The project will assess the impact of this program using the University of Florida Center for Precollegiate Education and Teaching.The project will incorporate an existing explicit stellar feedback model (Smuggle) into the existing AREPO cosmological simulation code. Smuggle models gas cooling, star formation, and stellar feedback. AREPO is the basis for the Illustric cosmological simulations. The project will self-consistently produce thousands of galaxies from within these simulations that can then be compared with observations. The bulk of the broader impacts of this project will be performed at the University of Florida. The project will establish a field trip program for middle school students in underserved school districts in Florida. The students will visit the local Santa Fe planetarium. The project will assess the impact of this program using the University of Florida Center for Precollegiate Education and Teaching.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.
