Collaborative Research: The Impacts of Massive Black Hole Formation and Evolution Pathways on Gravitational Wave Sources

该奖项是一个合作项目的一部分，该项目旨在了解大质量黑洞是如何在宇宙早期的星系中形成和生长的。该团队将使用计算机模拟早期宇宙中具有不同黑洞形成模型的星系的诞生和增长。然后，他们将寻找不同模型之间预测的引力波事件的差异。他们还将在模拟中搜索与黑洞增长和可能的引力波事件相关的预期光学事件。这个合作项目将研究宇宙模拟中的三种不同的黑洞播种机制，就像IllustrisTNG模拟中的星系形成模型一样。这些将通过流体动力学宇宙学模拟来追踪，以确定可以从合并的大质量黑洞的引力波探测和高红移星系的电磁观测中提取的天体物理信息。来自模拟的数据将公之于众。该项目推进了NSF宇宙大理想之窗的目标。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
