This award is part of a collaborative project to understand how massive black holes form and grow in galaxies in the early universe. The team will use computer simulations of the birth and growth of galaxies in the early universe with different black hole formation models. They will then look for differences in the predicted gravitational wave events between models. They will also search through the simulations for expected optical events that would be associated with the growth of black holes and possible gravitational wave events.This collaborative project will look at three different black hole seeding mechanisms in cosmological simulations with galaxy formation models as in the IllustrisTNG simulations. These will be traced through hydrodynamical cosmological simulations to determine the astrophysical information that can be extracted from gravitational wave detection of merging massive black holes and electromagnetic observations of galaxies at high redshifts. The data from the simulations will be made public.This project advances the goals of the NSF Windows on the Universe Big Idea.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.

该奖项是一个合作项目的一部分，该项目旨在了解早期宇宙中星系中的黑洞形成和增长。该团队将使用不同的黑洞形成模型在早期宇宙中使用计算机模拟星系的出生和生长。然后，他们将寻找模型之间预测的重力波事件的差异。他们还将在模拟中搜索与黑洞的生长和可能的重力波事件有关的预期光学事件。该协作项目将在宇宙学模拟中使用带有星系形成模型的三种不同的黑洞播种机制，如Illustristng模拟中。这些将通过流体动力学宇宙学模拟来追溯，以确定可以从合并大量黑洞的重力波检测中提取的天体物理信息，并在高红移处对星系的电磁观测。来自模拟的数据将公开。该项目促进了NSF Windows在宇宙大概念上的目标。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
