Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Investigating Galactic Cosmic Ray Ionization’s Contribution to Aerosol Formation on Neptune and a Potential Link to the Relationship Between Brightness and Solar Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Using Gravitational Lensing to Probe for Candidate Quintessential Galaxies in the Epoch of Reionization

The Astrophysical Journal
Understanding the properties of the first generation of galaxies is an ongoing challenge in observational astrophysics. James Webb Space Telescope deep-field observations have led to the identification of large numbers of galaxies within the Epoch of ...

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Authigenic Be Isotopes Record Circumpolar Deep Water Inflow and Subglacial Outflow in Antarctic Shelf Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Antarctic Ice Sheet (AIS) has recently undergone accelerating mass loss driven primarily by basal melting associated with Circumpolar Deep Water (CDW) inflow onto the continental shelf. However, temporal variability in CDW inflow and its role in mass loss from the AIS over longer timescales remain uncertain because the duration of the ...
