Multi‐Step Gravity Wave Propagation From a Tropospheric Vortex to the Ionosphere Near the Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan

Production of Secondary Electrons by Cosmic Ray Particles [PDF]

Nature, 1938
SOME early measurements of Anderson and Nedder-meyer1 show that the number of single secondary electrons ejected by cosmic ray particles from a metal plate is in reasonable agreement with that to be expected from direct elastic collisions. In a series of photographs we have observed the traversal of a 2 cm.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Simulation of subsurface particle radiation and leakage flux on the moon from solar energetic particles and galactic cosmic rays

European Physical Journal C: Particles and Fields
The moon is continuously bombarded by cosmic rays, primarily Galactic Cosmic Rays (GCR) and Solar Cosmic Rays, which generate complex secondary radiation in the lunar subsurface.

Non-variable cosmologically distant gamma-ray emitters as an imprint of propagation of ultra-high-energy protons

, 2011
The acceleration cites of ultra-high-energy (UHE) protons can be traced by the footprint left by these particles propagating through cosmic microwave background (CMB) radiation.

Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Energetic particles accelerated via turbulent magnetic reconnection in protoplanetary discs – I. Ionisation rates

Astronomy & Astrophysics
Context. Ionisation controls the chemistry, thermal balance, and magnetic coupling in protoplanetary discs. However, standard ionisation vectors such as stellar UV, X-rays, Galactic cosmic rays might not be efficient enough, as UV/X-rays are attenuated ...
