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...
The University of Chicago received a $366,748 Project Grant award from the National Science Foundation Division of Astronomical Sciences on September 1, 2021 to complete the project by August 31, 2024. The grant supports collaborative research on cosmic shear measurements on extremely large scales using the Dark Energy Camera. This award falls under the NSF's Mathematical and Physical Sciences program (CFDA 47.049), which aims to promote progress in these fields and strengthen the national...
The National Science Foundation (NSF) awarded a $291,840 Project Grant under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049) to the University of Chicago. The grant supports collaborative research to develop and apply new techniques for precisely measuring the motions of faint stars using ground-based survey telescopes, including the Dark Energy Camera (DECam) on the NSF's 4-meter Blanco Telescope. The research aims to provide the most accurate measurements of the...
This Project Grant award, valued at $481,791.00, was provided by the National Science Foundation (NSF) through its Mathematical and Physical Sciences (CFDA 47.049) federal grant program. The award aims to investigate the physical origin of satellite planes around the Milky Way and other nearby galaxies, which do not yet have a compelling explanation within the current Cold Dark Matter (CDM) paradigm of galaxy formation. The key objectives of this 3-year project include: 1) Developing models...
This National Science Foundation (NSF) Mathematical and Physical Sciences Program (CFDA 47.049) Project Grant award provides $251,928 to the University of Chicago to conduct collaborative research on combining galaxy and cosmic microwave background surveys to obtain precise and robust constraints on cosmology - the distribution of matter throughout the universe. The research team will analyze complementary measurements of galaxy positions, gravitational lensing of galaxies, gravitational lensing...
This Project Grant award, provided by the National Science Foundation (NSF) under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049), will support collaborative research by scientists at the University of Chicago and the University of Hawaii to precisely measure the distribution of matter in the universe. The $345,303 grant will fund the analysis of multiple complementary astronomical surveys, including the Dark Energy Survey, South Pole Telescope, and Atacama Cosmology...
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 $338,402 Project Grant was awarded by the National Science Foundation's (NSF) Division of Astronomical Sciences under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program. The objective of the award is to develop a comprehensive model that predicts the population of dwarf galaxies surrounding the Milky Way as a function of dark matter properties and early universe dynamics. This will enable near-field measurements of small-scale matter clustering, yielding...
This $419,979 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports collaborative research by the University of California, San Diego (UCSD) to reconstruct primordial density fluctuations and the population of dwarf galaxies surrounding the Milky Way. The research aims to leverage data on faint dwarf galaxies to constrain models of dark matter properties and early universe dynamics, including during cosmic inflation....
This $271,496 National Science Foundation project grant supports collaborative research on dwarf galaxies over cosmic time. The University of Arizona will investigate dwarf galaxy populations within five million parsecs and halfway across the observable universe using wide-field, high-resolution multi-object spectrometers in both hemispheres. An integral field unit spectrograph constructed with prior NSF funding, IFUM, will obtain the first measurements of star formation rates, metallicity,...
