The project aims to understand how certain radio waves launched into space can be amplified by energetic particles, which is critical for improving models of space weather phenomena and radiation belt dynamics. The award supports graduate and...
- The National Science Foundation (NSF) awarded a $515,885 Project Grant under the Geosciences Program (CFDA 47.050) to The Regents of the University of Colorado, doing business as the University of Colorado's Office of Contracts and Grants Division. The grant will support a 3-year research project to investigate the inward transport and energy-dependent penetration of energetic electrons (10s of keV to multi-MeV) from the Earth's outer radiation belt into the inner radiation belt. The research...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) project grant award of $148,179 made to the University of Texas at Arlington (UTA) aims to investigate the dynamics of fast plasma flows within the Earth's nightside magnetosphere and their effects on the upper atmosphere. The key research components include: The project uses a two-way coupled global MHD-PIC model to study the particle velocity distributions, field-aligned currents, and impacts on the ionosphere and...
This three-year, $969,646 National Science Foundation Project Grant in the Geosciences program (CFDA 47.050) supports research at the University of Texas at Dallas to study nonlinear interactions between energetic electrons and oblique whistler-mode chorus waves in Earth's outer radiation belt. The investigators will develop numerical models of oblique chorus wave packets and electron phase space density evolution. They will quantitatively compare model results with in-situ measurements from NASA's Van Allen Probes to address three scientific questions: how energetic electron phase space density evolves under nonlinear wave-particle interactions; whether observable distinctions exist between different electron harmonic resonances with magnetospheric chorus waves; and the respective roles of Landau and cyclotron resonances in shaping the outer radiation belt during events with intense oblique chorus waves. Important findings may include direct observational evidence of electron nonlinear resonances in distinct harmonics, advancing theoretical understanding. The award also supports early-career researchers and a graduate student, with research outcomes to be incorporated into public outreach and university classes.
