This Project Grant from the National Science Foundation Division of Astronomical Sciences will support research to develop more accurate non-local thermodynamic equilibrium (non-LTE) models for analyzing spectra of metal-poor red giant stars. The University of Chicago will receive $424,475 under the award, covering the period from September 1, 2022 to August 31, 2025. The investigators will enhance existing stellar spectral analysis tools by implementing non-LTE physics and machine learning...
This $145,866 Project Grant awarded by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research effort to study the interior structures of massive hot stars using a new technique called polarimetric asteroseismology. The grant, awarded on September 1, 2024, with a completion date of August 31, 2027, involves a research team from multiple institutions, including the Monterey Institute for Research in Astronomy, Florida Gulf...
The National Science Foundation (NSF) has awarded a $291,840 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program to the University of Chicago. This 3-year award, spanning September 1, 2024 to August 31, 2027, will support a collaborative research project to develop and apply new techniques for precisely measuring the motions of faint stars using ground-based survey telescopes. The research aims to provide critical data for understanding the formation...
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 $218,572 to San Francisco State University under the Mathematical and Physical Sciences federal grant program (CFDA 47.049) to characterize over 300 metal-poor star candidates observed in the Apache Point Observatory Galactic Evolution Experiment survey. The University will analyze and conduct follow-up observations of the metal-poor star candidates using the Lick and Keck telescopes to determine...
This National Science Foundation (NSF) Division of Astronomical Sciences Project Grant award of $457,353 to The Ohio State University supports a program of data analysis and modeling to interpret the elemental abundance patterns of stars in the Milky Way and its dwarf satellite galaxies. The research, which runs from September 1, 2023 to August 31, 2026, aims to build a coherent picture of the stellar and galactic-scale phenomena that govern the synthesis of chemical elements. This work will...
This $346,927 federal Project Grant award, provided by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049), will enable fundamental research on Cepheids and RR Lyrae variable stars. The researchers at Florida State University will analyze the properties of these pulsating stars to understand the history of the galaxies where they are found. This work will pave the way for further studies with the Vera Rubin Telescope, also known as the Legacy Survey...
This Project Grant from the National Science Foundation Division of Astronomical Sciences provides $243,204 to the University of California Santa Cruz to characterize metal-poor stars in the Apache Point Observatory Galactic Evolution Experiment survey. Under the Mathematical and Physical Sciences program (CFDA 47.049), the award will fund analysis of over 300 metal-poor star candidates identified in the APOGEE survey data. Follow-up observations will be conducted at Lick and Keck...
This five-year Project Grant from the National Science Foundation Division of Astronomical Sciences provides $527,050 to the University of Massachusetts Amherst to establish coherent frameworks for understanding massive galaxy formation and promote inclusive astronomy. Under the Mathematical and Physical Sciences program (CFDA 47.049), the investigator will use data from the Large Millimeter Telescope and Subaru Telescope to map the distribution of galaxies and molecular gas throughout...
