Electron Shot Noise on a Current Biased Antenna

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

Observations of the Latitude and Frequency Distributions of Equatorward‐Propagating Chorus Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Rising‐tone chorus elements are traditionally known to grow from low frequencies and extend to high frequencies. Using high‐resolution waveform measurements from the Van Allen Probes, we report a novel observation: equatorward‐propagating chorus waves at a few degrees in latitude are observed at high frequencies only.

Reanalysis of SKR Source Crossed by Cassini: Loss Cone Electrons as a Secondary Source of Free Energy

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Saturn's Kilometric Radiation (SKR) is a powerful non‐thermal radio auroral emission produced by the Cyclotron Maser Instability (CMI), which generates waves close to the local cyclotron frequency in a highly magnetized plasma from mildly relativistic electrons.

Spiky Bursts of Energetic Electron Beams Upstream of Nonstationary Quasi‐Perpendicular Shocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Energetic electron beams play a crucial role in collisionless shocks by driving upstream plasma waves and providing seed populations for diffusive shock acceleration. However, the processes responsible for their generation at quasi‐perpendicular shocks remain poorly understood.

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.
