This federal Project Grant award, valued at $330,000.00, was provided by the National Science Foundation (NSF) through its Mathematical and Physical Sciences (CFDA 47.049) program. The award was granted to Antonio Porras-Valverde to conduct a program of research and education at Yale University.

The key products and services to be delivered under this award include:

  • Research that will result in testable predictions of black hole formation channels, growth, and feedback, leveraging data from upcoming surveys such as the Legacy Survey of Space and Time.
  • Educational activities, where Porras will co-lead computational and professional development workshops for undergraduates with Yale graduate students.
  • Integration of the impact of continual seeding of intermediate mass black holes formed in dense nuclear star clusters into the Dark SAGE semi-analytic model, and analysis of its effects on scaling relations over time.
  • Calculations to quantify the variation in mass accretion between this new model and a fiducial Dark SAGE model, in order to predict observational signatures and the impact of this new growth channel on the cosmic assembly history of supermassive black holes.

This award reflects the NSF's mission to promote progress in the mathematical and physical sciences and strengthen the nation's scientific enterprise. The project is expected to be completed by June 30, 2028.
