ISNet: Decomposed Dynamic Spatio‐Temporal Neural Network for Ionospheric Scintillation Forecasts
Space Weather, Volume 23, Issue 6, June 2025.Abstract Accurate prediction of ionospheric scintillation is essential for ensuring the reliability of spaceborne and ground‐based radio wave technology infrastructures, including but not limited to navigation and communication systems. In this study, we propose a deep learning‐based Ionospheric Scintillation Network (ISNet), which can predict the ...

Filling the Magnetospheres of Weak Pulsars [PDF]
, 2019 Recent advances in numerical algorithms and computational power have enabled first-principles simulations of pulsar magnetospheres using Particle-in-Cell (PIC) techniques. These ab-initio simulations seem to indicate that pair creation through photon-photon collision at the light cylinder is required to sustain the pulsar engine.

Earth and Space Science, Volume 12, Issue 6, June 2025.Abstract To explore the hypothesis of a common source of variability in two time series, observers may estimate the magnitude‐squared coherence (MSC), which is a frequency‐domain view of the cross correlation. For time series that do not have uniform observing cadence, MSC can be estimated using Welch's overlapping segment averaging.

Anomalous Substorm Signatures During Sudden Solar‐Wind Pressure Enhancements
Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract Magnetospheric substorms, characterized by the rapid release of energy stored in the magnetotail, play a central role in space weather dynamics. These events are typically triggered by enhanced magnetic reconnection between the Earth's magnetic field and the interplanetary magnetic field (IMF).

The electron density at the midpoint of the plasmapause
Frontiers in Astronomy and Space SciencesThe high density plasmasphere in the magnetosphere is often separated from a lower density region outside of the plasmasphere, called the plasmatrough, by a sharp gradient in electron density called the plasmapause.

Electron radiation belt dynamics during magnetic storms and in quiet time
Solar-Terrestrial Physics, 2018 The paper discusses the outer electron belt dynamics, adiabatic and nonadiabatic mechanisms of increases and losses of energetic electrons. Under undisturbed conditions, the outer electron belt gradually empties: in the inner magnetosphere due to ...

Eos, Transactions American Geophysical Union, 1991 Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic

Electrospherics and magnetospherics [PDF]
Electrical Engineering, 1959 In the second part of a two-part article, additional experiments with small spheres of magnetic material are described. Not only are the results interesting in themselves, but also it is hoped that they may serve as analogs for such phenomena as Brownian movement, thermal movement of molecules, crystal formation, bacterial chaining, and others.

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.

Enhanced Energetic Neutral Atom Imaging
Frontiers in Astronomy and Space Sciences, 2019 Over the past two decades, instruments designed to image plasmas in energetic neutral atom (ENA) emission have flown in space. In contrast to typical satellite-based in situ instruments, ENA imagers provide a global view of the magnetosphere because they
