Pickup Ion–Mediated Magnetic Reconnection in the Outer Heliosphere
The Astrophysical Journal Letters, 2023 Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shock, and the heliopause.

Dependence of the IBEX Ribbon Geometry on Pitch-Angle Scattering outside the Heliopause [PDF]
, 2021 Interstellar Boundary Explorer (IBEX) observations of the “ribbon” of enhanced energetic neutral atom (ENA) fluxes show that it is a persistent feature that approximately forms a circle in the sky, likely formed from secondary ENAs whose source lies ...

An Anomalous Cosmic-Ray Mediated Termination Shock: Implications for Energetic Neutral Atoms
The Astrophysical Journal Letters, 2023 The Voyager 2 crossing of the termination shock indicated that most of the upstream energy from the thermal solar wind ions was transferred to pickup ions (PUIs) and other energetic particles downstream of the shock.

Voyager Observations of Electron Densities in the Very Local Interstellar Medium
The Astrophysical Journal, 2023 The two Voyager spacecraft have now been immersed in the very local interstellar medium for several years. Both spacecraft carry a plasma wave instrument capable of detecting plasma waves that yield electron density through the determination of the ...

A test for whether or not Voyager 1 has crossed the heliopause [PDF]
, 2014 The Voyager 1 spacecraft is currently in the vicinity of the heliopause, which separates the heliosphere from the local interstellar medium. There has been a precipitous decrease in particles accelerated in the heliosphere and a substantial increase in

Approximation of Daily AMS‐02 Spectra With Machine Learning Methods
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Journal of Geophysical Research: Space Physics, Volume 122, Issue 8, Page 7865-7890, August 2017., 2017 Abstract We discuss observations of the journey throughout the Solar System of a large interplanetary coronal mass ejection (ICME) that was ejected at the Sun on 14 October 2014. The ICME hit Mars on 17 October, as observed by the Mars Express, Mars Atmosphere and Volatile EvolutioN Mission (MAVEN), Mars Odyssey, and Mars Science Laboratory (MSL ...

Probing the Length of the Heliospheric Tail with Energetic Neutral Atoms (ENAs) from 0.52 to 80 keV
The Astrophysical Journal Letters, 2023 The shape of the heliosphere is currently under active debate. Energetic neutral atoms (ENAs) offer the best method for investigating the global structure of the heliosphere.
