The dissipation of solar wind turbulent fluctuations at electron scales [PDF]

, 2011
We present two-dimensional fully-kinetic Particle-in-Cell simulations of decaying electromagnetic fluctuations. The computational box is such that wavelengths ranging from electron to ion gyroradii are resolved.

New Constraints on the Jovian Narrowband Radio Components From Juno/Waves Observations and 3D Geometrical Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Measurements of Waves instrument onboard the Juno spacecraft suggest that narrowband kilometric radiation (nKOM; 20–141 kHz) and narrowband low‐frequency radiation (nLF; 5–70 kHz) are generated within the plasma near the Io plasma torus (IPT) in low‐latitude regions.

On nonlinear Alfv\'en-cyclotron waves in multi-species plasma

, 2010
Large-amplitude Alfv\'en waves are ubiquitous in space plasmas and a main component of magnetohydrodynamic (MHD) turbulence in the heliosphere. As pump waves they are prone to parametric instability by which they can generate cyclotron and acoustic ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Compressive high-frequency waves riding on an Alfv\'en/ion-cyclotron wave in a multi-fluid plasma

, 2011
In this paper, we study the weakly-compressive high-frequency plasma waves which are superposed on a large-amplitude Alfv\'en wave in a multi-fluid plasma consisting of protons, electrons, and alpha particles.

Reconstruction of Two‐Dimensional Magnetohydrodynamic and Hall Magnetohydrodynamic Equilibria in Space Using Physics‐Informed Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract We present a novel data analysis technique based on physics‐informed neural networks (PINNs) to reconstruct two‐dimensional (2D) magnetohydrodynamic (MHD) and Hall MHD equilibria in a space plasma from in situ spacecraft measurements. Our method incorporates the steady‐state MHD or Hall MHD equations—a set of partial differential equations ...
