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.

星系中的恒星是由冷气体形成的，但恒星形成的行为和这些恒星的演化可以重新加热气体或将其吹走。这种对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部分。该项目将使用他们自己的模型在更大的宇宙学模拟中进行恒星反馈。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，以更好地理解宇宙学中反馈的影响。该项目还将为佛罗里达州服务欠缺学区的中学生建立实地考察计划。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评估该计划的影响。该项目将把现有的显式恒星反馈模型（Smuggle）纳入现有的 AREPO 宇宙学模拟代码中。走私模型气体冷却、恒星形成和恒星反馈。 AREPO 是说明宇宙学模拟的基础。该项目将从这些模拟中自洽地产生数千个星系，然后可以将其与观测结果进行比较。该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的学区的中学生建立一个实地考察计划。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前教育和教学中心评估该计划的影响。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
