Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract The limits of detection for earthquake surface deformation in the spatial domain have improved with advances in remote sensing imagery data availability, resolution, and analysis. Sub‐pixel correlation and digital elevation model (DEM) differencing from sub‐meter, earthquake‐spanning satellite optical imagery has enhanced surface rupture ...

Arbitrary amplitude ion-acoustic solitary and shock waves in an unmagnetized electron–proton–ion nonthermal plasma [PDF]
AIP AdvancesThis study thoroughly examines the features of arbitrary amplitude ion-acoustic nonlinear structures, including both solitary and shock waves (double layers), in an unmagnetized electron–proton–ion plasma where electrons follow Cairns distributions and ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Atmospheric gravity waves (GWs) are believed to transport energy and momentum between different regions of the atmosphere. Historically, observations of these waves from both ground and space have been relatively abundant at altitudes up to the lower thermosphere, and somewhat less abundant in the upper thermosphere and F‐region ionosphere ...

Temperatures of Jupiter’s Upper Atmosphere: The Role of the Planetary Magnetic Field
The Astrophysical Journal LettersThe primary source of heating in the upper atmospheres (thermospheres) of giant planets has been the subject of long debate. The conundrum (or “energy crisis”) consists in observed thermosphere temperatures at low and midlatitudes exceeding values ...

Infrared Rugates by Molecular Beam Epitaxy [PDF]
Rugates are optical structures that have a sinusoidal index of refraction (harmonic gradient-index field). As their discrete high/ low index filter counterparts, they can be used as narrow rejection band filters. However, since rugates do not have abrupt

Steady-State Magnetohydrodynamic Flow Around an Unmagnetized Conducting Sphere [PDF]
, 2014 The non-collisional interaction between conducting obstacles and magnetized plasma winds can be found in different scenarios, from the interaction occurring between regions inside galaxy clusters to the interaction between the solar wind and Mars, Venus,

A Direct Simulation Monte Carlo–Driven Photochemical Model of Callisto’s Ionosphere
The Planetary Science JournalHere we present a photochemical model of Callisto’s ionosphere with inputs supplied by a direct simulation Monte Carlo model of its neutral atmosphere. We compare a model that considers interactions with photons as the sole external ionization mechanism ...
