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 federal Project Grant award, totaling $105,646, was provided by the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049) to support a collaborative research project led by Seattle University. The research aims to confirm the origins of stars in the Milky Way's metal-poor bulge by spectroscopically measuring the elemental abundances of candidate globular cluster tidal debris stars. The project will involve obtaining detailed observations of...
This Project Grant award from the National Science Foundation's Division of Astronomical Sciences, under the Mathematical and Physical Sciences program (CFDA 47.049), will fund a $697,725 project over 3 years to detect and characterize new low-mass planets orbiting distant stars. The award will support a team at San Francisco State University, which will use the EXPRES high-precision radial velocity spectrograph to find small, long-period planets in systems similar to our own solar system....
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 $153,169 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research project at Saint Martins University that aims to study the disintegration of globular clusters and their contribution to the metal-poor bulge of the Milky Way galaxy. The research team, comprising investigators from four primarily undergraduate institutions, will obtain detailed observations of 3,000 stars to measure their...
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...
This three-year, $153,949 Project Grant from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) supports research to create a unique catalog of open star clusters in the Milky Way disk through observations and analysis. The University of Utah will observe nearly all suitable open star clusters using spectroscopy from the Sloan Digital Sky Survey V and astrometry from the Gaia satellite. Additional high-resolution spectroscopy will measure abundances of...
This Project Grant from the National Science Foundation Division of Astronomical Sciences totaling $458,054 will support research exploring the gas-phase properties of galaxies using data from the Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point survey. Principal Investigator Scudder will analyze spatially resolved gas-phase metallicities in 10,000 galaxies from archival integral field spectra. Contamination from active galactic nuclei will be assessed. Calibration methods will...
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 $109,108 federal Project Grant award from the National Science Foundation's (NSF) Division of Astronomical Sciences under the Mathematical and Physical Sciences (CFDA 47.049) program supports a collaborative research project titled "The Disintegration of Clusters and their Contribution to the Metal-Poor Bulge" at Western Washington University. The research aims to confirm the origin of stars from disrupted globular clusters that have contributed to the Milky Way's bulge. The...
