This $539,342 National Science Foundation (NSF) Project Grant, awarded under the Mathematical and Physical Sciences (CFDA 47.049) program, supports research into the unexpectedly high number of bright, luminous galaxies observed during the early universe's "cosmic dawn" period. The principal investigators will use advanced cosmological simulations to study the physical conditions in these massive, high-redshift dark matter halos that may enable extreme star formation rates up to 100...
This $578,577 Project Grant was awarded by the National Science Foundation (NSF) Division of Astronomical Sciences under the Mathematical and Physical Sciences program (CFDA 47.049) on August 15, 2023. The award supports collaborative research to spatially resolve the mechanisms driving star formation quenching in galaxies using molecular gas observations. The project will leverage recently completed galaxy surveys and state-of-the-art simulations to investigate whether the cessation of star...
This $507,210 Project Grant was awarded by the National Science Foundation (NSF) Division of Astronomical Sciences under the Mathematical and Physical Sciences program (CFDA 47.049). The grant supports a coordinated experimental, theoretical, and observational study led by the Smithsonian Astrophysical Observatory to advance the understanding of complex carbon chemistry in interstellar space. The key objectives are to: 1) Identify new organic molecules and determine the chemical pathways that...
This three-year, $130,077 Project Grant from the National Science Foundation's Division of Astronomical Sciences, under the Mathematical and Physical Sciences program (CFDA 47.049), will fund collaborative research to better understand galaxy cluster merger dynamics. The Smithsonian Institution Astrophysical Observatory will analyze observational data and hydrodynamical simulations of ten galaxy clusters to map the projected total mass density, intracluster medium emissivity and temperature,...
This $540,758 Project Grant award from the National Science Foundation (NSF) Division of Astronomical Sciences supports research at Northwestern University focused on advancing the understanding of star formation, the interstellar medium (ISM), and stellar winds in galaxies with bursty versus steady star formation rates. The key research objectives are to: 1) assess the applicability of equilibrium disk and pressure balance models for the Kennicutt-Schmidt star formation law, 2) examine the...
This National Science Foundation (NSF) grant award under the Mathematical and Physical Sciences program (CFDA 47.049) provides $270,796 to the University of Massachusetts to conduct a comprehensive survey of a large sample of candidate dusty starburst galaxies in the early universe. The main objectives are to determine accurate redshifts and positions, and define a statistically significant sample of galaxies at z > 6. This will involve deep optical and near-infrared follow-up observations...
This National Science Foundation (NSF) Division of Astronomical Sciences Project Grant award of $433,221.00 to the University of Illinois aims to advance understanding of star formation processes in galaxies. The research team will spatially resolve connections between the cold molecular gas fuel and declining star formation rates in aging galaxies, using a combination of observational data and computer simulations. They will leverage recently completed surveys and state-of-the-art...
This $179,648 federal Project Grant award, funded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) program, supports a collaborative research project exploring the formation of multiple star systems. The principal investigators at the University of Arizona will use computer simulations to study the physical processes responsible for the creation of binary and higher-order star systems, compared to the formation of single star systems like our...

This federal Project Grant award from the National Science Foundation (NSF) Mathematical and Physical Sciences (CFDA 47.049) program provides $365,771 to the University of California Santa Cruz to enhance models of stellar astrophysics. The project aims to improve predictions of stellar evolution and better understand the impacts of solar activity on Earth by simulating turbulent plasma flows within stars using advanced computational tools. The research will refine rotational mixing models...

This National Science Foundation (NSF) Federal Grant Award, funded through the Mathematical and Physical Sciences (CFDA 47.049) program, will support a $447,644 project led by the Smithsonian Astrophysical Observatory (SAO). The project aims to study the lifecycle of gas and young stars in the solar neighborhood, generating an integrated 3D model to enable comparisons between galactic and extragalactic star formation. The key products and services to be delivered include:

  1. Leveraging topological data analysis techniques to produce 3D spatial models of gaseous features (e.g. clouds, voids) detected in recent 3D dust maps.
  2. Linking 3D dust maps with gas dynamics to generate new models of gas flows around these features.
  3. Developing a pipeline to analyze ages and masses of nearby young stellar clusters, providing new insights on the relationship between gas features and star formation/supernova feedback.

These data products will be publicly released and incorporated into an interactive 3D visualization dashboard to allow astronomers and the public to explore the 3D views of gas and young stars in the solar neighborhood. The project, which runs from May 2025 through April 2030, will also support a graduate student, postdoctoral scholar, and two post-baccalaureate students.
