Plasma Turbulence in the Near-Sun and Near-Earth Solar Wind: A Comparison via Observation-Driven 2D Hybrid Simulations

Universe, 2022
We analyse two high-resolution 2D hybrid simulations of plasma turbulence with observation-driven initial conditions that are representative of the near-Sun and the near-Earth solar wind. The former employs values of some fundamental parameters that have

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

A Model for Nonthermal Particle Acceleration in Relativistic Magnetic Reconnection

The Astrophysical Journal Letters, 2023
The past decade has seen an outstanding development of nonthermal particle acceleration in magnetic reconnection in magnetically dominated systems, with clear signatures of power-law energy distributions as a common outcome of first-principles kinetic ...
