The University of California, Los Angeles (UCLA) has been awarded an $84,826 grant by a civilian federal agency's Shared Services Center to develop a unified empirical framework characterizing ultra-low frequency (ULF) modulated electromagnetic ion cyclotron (EMIC), equatorial chorus (ECH), and whistler-mode chorus waves, and their collective effects on particle dynamics. The research initiative, which commenced on July 1, 2025, is scheduled for completion by June 30, 2026, and will be conducted...
This is a $463,067 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA) to investigate the role of electromagnetic ion cyclotron (EMIC) waves and the magnetopause in the rapid dropouts of ultrarelativistic electrons in the Earth's radiation belt. The research aims to address key goals in NASA's Heliophysics Decadal Survey related to understanding the dynamics and coupling of the Earth's magnetosphere. The grant supports...
This federal contract award, with ID NNX16AG21G, was granted by the Shared Services Center (an alternate name for the National Aeronautics and Space Administration) to the University of California, Los Angeles (UCLA) to conduct research on the relation between laboratory-generated whistler-mode waves and whistler-mode chorus waves observed in the near-Earth space environment. The $610,772.71 grant falls under the NASA H-TIDES program, which supports studies aimed at integrating theory, modeling,...
This is a $489,235 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA) to conduct research on ultra-low-frequency (ULF) waves in the Earth's inner magnetosphere and their connection to substorms. The research aims to understand the generation of compressional PI2 waves in the tail region of the magnetosphere by fast plasma flows and the inward propagation of these waves to the inner magnetosphere. The grant does not have a...
This is a grant award from the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA) valued at $194,947.67. The grant is for research on the "Oscillations of Magnetospheric Field Lines with High Azimuthal Wavenumbers (M)" and how they relate to solar wind conditions. The research aims to quantify the occurrence and characteristics of these high-m waves in the magnetosphere, which are important for understanding the dynamics of...
The National Aeronautics and Space Administration (NASA) awarded a $520,129 grant to The Regents of the University of Colorado, doing business as the University of Colorado-Denver, to conduct research on whistler mode waves and their influence on radiation belt dynamics. The research seeks to understand the prevalence and impact of cold plasma density structures on the propagation and interactions of chorus waves, a type of whistler mode wave, in the Earth's magnetosphere. The project will...
This federal grant award to the University of California, Los Angeles (UCLA) is to support research on the interactions between ion cyclotron waves and the lunar exosphere. The $310,864.40 grant, awarded by the National Aeronautics and Space Administration (NASA), aims to address key science questions about the morphology of these waves, their excitation by pickup ions, and the insights they can provide about the loss and modification of the lunar exosphere. The research leverages data from...
This federal contract award with ID NNX16AF76G was granted by the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA) to conduct research on the generation of electromagnetic ion cyclotron (EMIC) waves in the Earth's magnetosphere. The $433,267.27 grant aims to determine the conditions under which EMIC waves form and quantify their effects on the loss of relativistic electrons in the outer radiation belt and ring current ions. The research...
This is a grant award from the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA), for a research project to study the propagation of impulses in the Earth's magnetosphere. The $471,045.26 grant aims to quantitatively evaluate the travel time of sudden impulses and nightside transients in the magnetosphere using data from several NASA and other agency missions. The investigation addresses fundamental physics questions and seeks to validate...
This federal grant award from the National Aeronautics and Space Administration (NASA) to the University of California, Los Angeles (UCLA) provides $430,716.51 to study the role of whistler-mode chorus waves in driving the dynamics of energetic electrons in the Earth's magnetosphere. The research aims to characterize the global distribution of chorus waves by combining data from multiple spacecraft missions. This will allow developing statistical models to parameterize chorus wave properties as a function of location, solar wind conditions, and geomagnetic activity. The resulting diffusion coefficients will then be incorporated into a radiation belt simulation code to improve understanding of how chorus waves affect the acceleration and loss of energetic electrons. This grant does not have a set-aside designation and is being performed at UCLA's facilities in Los Angeles, California.
