Multisatellite studies of ULF waves

Advances in Space Research, 1988
Multisatellite studies of ULF waves are reviewed, with a special emphasis on compressional Pc 5 waves. The observations of the radial extent, azimuthal wave number and the field-aligned standing wave structure of the waves are described. When combined with plasma data, the waves appear to be consistent with drift-mirror waves originating from the ...

Mother tongue instruction as a sticky object: The making of a register of denunciation

Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract This article examines the making of a political register to denounce mother tongue instruction (MTI) in Sweden. Nationally mandated since 1977, MTI is a state‐sponsored, curriculum‐stipulated subject for minority pupils of over 187 languages other than Swedish.

Modulation of Whistler-mode Waves in the Solar Wind in the Vicinity of Earth’s Moon

The Astrophysical Journal
Ultra-low-frequency (ULF) waves are known to modulate high-frequency whistler-mode waves within the Earth’s magnetosphere. Periodic bursts of whistler-mode waves are excited in association with ULF perturbations of plasma density and magnetic field.

Accounting for Variability in ULF Wave Radial Diffusion Models [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractMany modern outer radiation belt models simulate the long‐time behavior of high‐energy electrons by solving a three‐dimensional Fokker‐Planck equation for the drift‐ and bounce‐averaged electron phase space density that includes radial, pitch‐angle, and energy diffusion.

Global Impacts of Ultra‐Low‐Frequency Waves: 1. Thermospheric Responses and Traveling Atmospheric Disturbances

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...

Listening to the Magnetosphere: How Best to Make ULF Waves Audible

Frontiers in Astronomy and Space Sciences, 2022
Observations across the heliosphere typically rely on in situ spacecraft observations producing time-series data. While often this data is analysed visually, it lends itself more naturally to our sense of sound.

Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

Abrupt Disappearance of Plasmaspheric Hiss Inside the Magnetic Dip

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Plasmaspheric hiss plays an important role in radiation belt electron dynamics, and its excitation and propagation have long attracted attention. During a substorm, Van Allen Probe B observed the disappearance of plasmaspheric hiss at the magnetic dip, which was driven by the injection of energetic protons.

Global modeling of ULF waves at Mercury [PDF]

Geophysical Research Letters, 2015
AbstractULF waves in the ion cyclotron frequency range waves are regularly observed at Mercury's magnetosphere. Although previous statistical studies have shown that ULF waves are primarily compressional near the equator and transverse with linear polarization at higher latitude, the underlying reason for this distribution of wave polarization has not ...
