This National Science Foundation (NSF) Division of Physics Project Grant, under the Mathematical and Physical Sciences (CFDA 47.049) program, was awarded to the University of Tennessee in the amount of $330,000 on August 1, 2023. The project will conduct state-of-the-art simulations to differentiate electron-capture and core-collapse supernovae, modeling the formation of neutron stars, neutrino emission, and nucleosynthesis. The detailed nuclear reaction network models will be extended through...
This is a $450,000 Project Grant awarded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program. The grant supports research by the University of Tennessee focused on two key objectives: Incorporating magnetic fields into the university's leading core collapse supernova simulation models, known as THORNADO. This will advance the understanding of core collapse supernovae, which are the explosive deaths of massive stars and a major...
This $450,000 National Science Foundation (NSF) Division of Physics Project Grant, awarded on August 1, 2023, will fund theoretical research and modeling to further the understanding of neutrinos and their role in multi-messenger astrophysics. Key focus areas include the physics of neutrinos from core collapse supernovae, predictions of the diffuse flux of cosmological supernovae, and interpretation of the observed flux of TeV-PeV neutrinos from outside our galaxy. The research aims to develop...
This $325,777 federal Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) will support a collaborative research effort to study nearby cosmic explosions, known as supernovae, from their earliest moments. The research team will enhance its rapid survey capabilities to promptly identify and study new supernovae in nearby galaxies, taking advantage of a network of small telescopes. This will enable the discovery of...
This Project Grant award of $300,000.00 from the National Science Foundation's (NSF) Division of Physics, under the Mathematical and Physical Sciences (CFDA 47.049) Federal Grant Program, supports the development of high-fidelity computational methods and software frameworks for simulating core-collapse supernovae and neutron star mergers.
The project, titled "ELEMENTS: Toolkit for High-Order Neutrino-Radiation Hydrodynamics in General Relativity," will implement novel numerical algorithms and software elements for relativistic, spectral two-moment neutrino kinetics within the open-source THORNADO toolkit. The new methods, based on discontinuous Galerkin discretization and implicit-explicit time stepping, will enable large-scale multi-physics modeling of these catastrophic astrophysical events on high-performance computing systems. The project aims to improve understanding of core-collapse supernovae and provide better predictions of their neutrino and gravitational wave signatures, while also training the next generation of computational scientists in a multidisciplinary research environment.
