- This three-year Project Grant from the National Science Foundation Division of Astronomical Sciences, under the Mathematical and Physical Sciences program (CFDA 47.049), provides $465,508 to the University of Massachusetts Boston to generate new spectroscopic data on small silicon carbide molecules that are key reactive intermediates in the formation of dust around evolved stars. Using advanced laser spectroscopy techniques including two-dimensional laser induced fluorescence and stimulated...
- This $557,211 Project Grant awarded by the National Science Foundation (NSF) Division of Astronomical Sciences supports research to better understand the multi-phase, multi-scale circumgalactic medium (CGM) - the diffuse gas surrounding galaxies. The principal investigator will conduct high-resolution computer simulations to study the physics underlying the formation, evolution, and properties of galactic atmospheres and clouds, with a focus on turbulent fragmentation, magnetic field effects,...
- This Project Grant award from the National Science Foundation's (NSF) Division of Astronomical Sciences, under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049), provides $526,998 to Yale University to conduct research on the star formation process. The primary objectives are to: Use millimeter-wave observations from the Atacama Large Millimeter Array (ALMA) to probe the structure and evolution of star-forming regions, specifically examining how material is funneled from...
- This National Science Foundation (NSF) Project Grant, titled "COLLABORATIVE RESEARCH: PROTOCOMETS TO PROTOPLANETS: CONNECTING THE CHEMICAL ECOSYSTEMS OF PLANET-FORMING DISKS ACROSS THE SPECTRUM", will support research to characterize the carbon monoxide (CO) gas in disks surrounding new-born stars. The $213,635 award, effective September 15, 2024 through August 31, 2027, will utilize data from ground-based observatories like the Atacama Large Millimeter Array (ALMA) and the Keck...
- This National Science Foundation (NSF) Division of Astronomical Sciences Project Grant, awarded on August 1, 2023 for $242,524, supports collaborative research by the University of Arizona aimed at exploring the composition of exoplanetary systems through observations and modeling of dusty circumstellar disks around other stars. The research goal is to determine the composition of rocky material orbiting other stars by analyzing the dust released from colliding rocks, which reflects and...
- This $346,372 National Science Foundation project grant supports research to better understand the interaction between interstellar gas, supernova explosions, and massive young stars in nearby galaxies. Funded under the Mathematical and Physical Sciences program (CFDA 47.049), the award will support observation, processing, and analysis associated with the Local Group L-Band Survey, an 1,800-hour Very Large Array survey of six northern Local Group galaxies including Andromeda. The survey will...
This $396,000 Project Grant award from the National Science Foundation (NSF) Division of Astronomical Sciences supports observational and laboratory studies of the evolution of circumstellar material from late-stage stellar evolution. The primary objectives are to: 1) Conduct a broadband millimeter-wave survey to analyze the carbon budget and isotope ratios in the carbon-rich envelope of the asymptotic giant branch (AGB) star IRC+10216; 2) Perform laboratory measurements of the rotational spectra of new metal-bearing carbides to aid their identification in circumstellar envelopes; 3) Analyze high-resolution images of the oxygen-rich envelope of VY Canis Majoris to understand the influence of the carbon-to-oxygen ratio; and 4) Evaluate the molecular and isotopic composition of a diverse sample of carbon-rich and oxygen-rich protoplanetary nebulae and planetary nebulae through radio astronomical observations. This research aims to elucidate how molecular material evolves from the AGB phase through the protoplanetary nebula and planetary nebula phases, and advance understanding of how stellar ejecta enrich the diffuse interstellar medium. The award also supports training of graduate and undergraduate students in radio astronomy and laboratory astrophysics techniques.
