Joseph Simon is awarded an NSF Astronomy and Astrophysics Fellowship to carry out a program of research and education at the University of Colorado. Combining pulsar timing array (PTA) measurements of the gravitational wave (GW) background with electromagnetic observations of galaxy mergers, Simon will model how black holes (BH) merge to form supermassive black holes (SMBH). Results from this project will allow astronomers to better understand how SMBH grow in mass. Simon will also provide research mentoring to undergraduate students and engage them in a program of outreach activities to local middle schools and high schools serving under resourced communities. Hints of the GW background emerging in PTA data appear inconsistent with theoretical predictions neglecting the contributions from BH-BH mergers and imply that SMBHs are more massive, or merge more frequently than previously thought. In this project, Simon will incorporate the best available observations of galaxy mergers and the SMBH mass function alongside a new prescription for the binary evolution timescale into his modeling framework for the binary SMBH population and the GW background. He will first use his refined models to extract the binary evolution timescale from PTA data. He will then combine the electromagnetic observations of galaxy mergers and the SMBH mass function with PTA observations to conduct the first multi-messenger measurement of SMBH mass growth due to BH-BH mergers. 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.

约瑟夫·西蒙（Joseph Simon）被授予NSF天文学和天体物理学奖学金，以在科罗拉多大学进行研究和教育计划。 Simon结合了重力波（GW）背景的脉冲星定时阵列（PTA）测量值，即银河合并的电磁观测，Simon将建模黑洞（BH）合并以形成超质量黑洞（SMBH）。 该项目的结果将使天文学家能够更好地了解SMBH的质量如何增长。 西蒙还将为本科生提供研究指导，并向他们与资源不足社区的当地中学和高中进行外展活动计划。 PTA数据中出现的GW背景的提示似乎与理论预测忽略了BH-BH合并的贡献不一致，这意味着SMBHS比以前想象的更大，或更频繁地合并。 在这个项目中，西蒙将将最佳的星系合并和SMBH质量功能的可用观察以及二进制进化时间尺度的新处方纳入其二进制SMBH人群和GW背景的建模框架。他将首先使用他的精制模型从PTA数据中提取二进制演化时间尺度。然后，他将将星系合并和SMBH质量功能的电磁观测与PTA观测值结合在一起，以进行首次通过BH-BH合并引起的SMBH质量生长的多通信测量。 该项目促进了NSF Windows在宇宙大想法上的目标。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审查标准，被认为值得通过评估来获得支持。
