ULF Waves above the Nightside Auroral Oval during Substorm Onset [PDF]

, 2016
This chapter reviews historical ground-based observations of ultra-low-frequency (ULF) waves tied to substorms, and highlights new research linking these ULF waves explicitly to substorm onset itself.

Frequency Extensions of Auroral Kilometric Radiation: The Key to Unlocking Earth's Radio Response to Substorms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Auroral kilometric radiation (AKR) provides a sensitive probe of magnetospheric dynamics during substorms. We analyze an extended data set of AKR bursts observed by the WIND spacecraft to investigate how the frequency structure of AKR responds to substorm onset and evolution.

Propagation Velocities and Growth Rates of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Foreshock of Earth

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Short Large‐Amplitude Magnetic Structures (SLAMS) are believed to play important roles in the physics governing the formation of quasi‐parallel shocks. These isolated non‐linear structures, frequently observed in the foreshock, have been suggested to be building blocks for the shock and have been shown to drive shock reformation. In this work,

The modulation of electromagnetic ion cyclotron waves by Pc 5 ULF waves [PDF]

Annales Geophysicae, 2009
The modulation of electromagnetic ion cyclotron (EMIC) waves by longer-period ULF waves has been proposed as a method for producing pearl structured Pc 1–2 EMIC waves.

Characterization of Mercury's Atomic and Molecular Hydrogen Exosphere and the First Detection of H2 Ions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...

10 May 2024 Gannon Storm: Connecting Energy Flux With Field Aligned Currents and Cross Polar Cap Potential

Space Weather, Volume 24, Issue 3, March 2026.
Abstract A simulation of the 10 May 2024 geomagnetic storm is used to investigate the theory of cross polar cap potential (CPCP) saturation in Earth's magnetosphere‐ionosphere system. THEMIS B (ARTEMIS P1) satellite magnetic field and plasma measurements at lunar distance upstream in the solar wind drives the Space Weather Modeling Framework (SWMF) in ...

Ultra-relativistic electron flux enhancement under persistent high speed solar wind stream

Frontiers in Astronomy and Space Sciences
The physical mechanisms usually applied to explain the relativistic electron enhancement have been delved into to elucidate non-adiabatic electron acceleration resulting in the ultra-relativistic electron population observed in the outer radiation belt ...

Chiral dynamics in few-nucleon systems [PDF]

, 2000
We employ the chiral nucleon-nucleon potential derived using the method of unitary transformation up to next-to-next-to-leading order (NNLO) to study bound and scattering states in the two-nucleon system.

INPRESS: INvasive PRESSure Monitoring Knowledge and Practice Survey

Nursing in Critical Care, Volume 31, Issue 2, March 2026.
ABSTRACT Background In patients on Intensive Care Units (ICU), invasive arterial pressure monitoring with closed transducer systems is widely used, yet the accuracy of measurement depends on correct zeroing, levelling and interpretation of arterial waveforms.
