The University of Chicago has been awarded a $459,219 Project Grant from the National Science Foundation (NSF) Division of Astronomical Sciences under the Mathematical and Physical Sciences program (CFDA 47.049). This 3-year award aims to conduct deep spectroscopy and photometry using the Magellan Telescope to derive metallicities of 50-200 main-sequence turn-off stars in four nearby ultra-faint dwarf galaxies. The goal is to reconstruct the formation histories of these ancient, metal-poor...
This $153,169 National Science Foundation (NSF) Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research project led by a team of investigators from four primarily undergraduate universities. The project aims to confirm the origins of metal-poor stars in the Milky Way's bulge by spectroscopically measuring the elemental abundances of stars that were likely stripped from disrupted globular clusters. By identifying the location of these...

This Project Grant from the National Science Foundation Division of Astronomical Sciences provides $304,225 to the University of Florida and the University of Chicago from September 1, 2022 through August 31, 2025. The funding supports research under the Mathematical and Physical Sciences program to advance understanding of stellar formation history through non-local thermodynamic equilibrium modeling of elemental abundances in metal-poor red giant stars.

Specifically, the universities will collaborate to create more accurate non-LTE models, apply machine learning techniques to efficiently emulate non-LTE grids, and derive stellar parameters and chemical compositions from large spectroscopic surveys. The results will be used to analyze enormous datasets and produce user-friendly, publicly available codes. The funding will also support opportunities for underrepresented K-12 students and undergraduates to gain research experience in astronomy. Overall, this collaborative work aims to provide a better understanding of the history of star formation in the Milky Way galaxy through improved analysis of elemental abundances in old stars.
