Electron Energization by Dispersive Alfvén Waves in the Cusp

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The propagation of kinetic Alfvén waves (assumed sourced from intermittent dayside reconnection) is investigated with a gyrofluid‐kinetic electron model compared with Cluster observations. These observations reveal electron distributions that are preferentially field‐aligned or field‐opposed, with signatures that are unidirectional or ...

Direct Radiation Belt Injections and Their Auroral Counterparts

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a case study of a moderate geomagnetic storm, which exhibits an abrupt relativistic enhancement in the heart of the radiation belt accompanied by low‐latitude purple auroral emission. The relativistic enhancement occurs on a timescale of tens of minutes and reaches MeV energies deep within the inner magnetosphere. The enhancement is

Whistler Chorus Amplification in the Magnetosphere: The Nonlinear Free‐Electron Laser Model and the Ginzburg‐Landau Equation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a novel nonlinear model for whistler‐mode chorus amplification based on the free‐electron laser (FEL) mechanism. First, we derive the nonlinear collective variable equations for the whistler‐electron interaction. Consistent with in situ satellite observations, these equations predict that a small seed wave can undergo exponential ...
