Extreme Magnetopause Deformation Induced by High‐Speed Jet From Foreshock Transient

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract This study presents comprehensive observations of intense high‐speed jets (HSJs) and their global impacts on the inner magnetosphere and ionosphere, using multi‐satellite and ground‐based observations. Cluster‐4, located near the bow shock, observed signatures associated with foreshock transients generated by a solar wind directional ...

Cosmic-ray Acceleration and Propagation

, 2015
The origin of cosmic rays (CRs) has puzzled scientists since the pioneering discovery by Victor Hess in 1912. In the last decade, however, modern supercomputers have opened a new window on the processes regulating astrophysical collisionless plasmas ...

Statistical Analysis of Multiple Bow Shock Crossings at Mars

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We conduct a statistical analysis of multiple bow shock (BS) crossings at Mars. Data from the magnetometer (MAG) and Solar Wind Ion Analyzer (SWIA) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft from its first 2 years in orbit is used to identify flapping events.

Nurturing breakthroughs: lessons from complexity theory [PDF]

, 2018
A general theory of innovation and progress in human society is outlined, based on the combat between two opposite forces (conservatism/inertia and speculative herding "bubble” behavior).

Automated Bow Shock Identification and Multi‐Spacecraft Timing Using Magnetospheric Multiscale (MMS) Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Utilizing 8 years of dayside Magnetospheric Multiscale (MMS) mission plasma region identifications, we present an automatically identified and manually verified data set of 2,594 bow shock crossings in MMS burst‐mode. For each bow shock crossing, we identify the bow shock ramp in each MMS probe using two automated methods and apply multi ...

Observations of Electron Vorticity in the Inner Plasma Sheet [PDF]

, 2011
From a limited number of observations it appears that vorticity is a common feature in the inner plasma sheet. With the four Cluster spacecraft and the four PEACE instruments positioned in a tetrahedral configuration, for the first time it is possible to

Local Time Dependence of High‐Latitude Pc5 Wave Activity Driven by Interplanetary Shocks and Foreshock Transients, Using a New ULF Index

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present a study of ground‐based Pc5 ultra‐low frequency (ULF) wave response to over 400 interplanetary (IP) shocks and 18 foreshock transients. We investigated the local time dependence of magnetospheric Pc5 wave power generated by IP shocks and foreshock transients and whether this dependence is related to the impact angle of IP shocks and

Plasmas in Gamma-Ray Bursts: particle acceleration, magnetic fields, radiative Processes and environments

, 2019
Being the most extreme explosions in the universe, gamma-ray bursts (GRBs) provide a unique laboratory to study various plasma physics phenomena. The complex lightcurve and broad-band, non-thermal spectra indicate a very complicated system on the one ...

Occurrence of Non‐Stationarity at Earth's Quasi‐Perpendicular Bow Shock

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Collisionless shocks can exhibit non‐stationary behavior even under steady upstream conditions, forming a complex transition region. Ion phase‐space holes, linked to shock self‐reformation and surface ripples, are a signature of this non‐stationarity.
