Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

The Nature of Emission-Line Galaxies in Hierarchical Cosmologies [PDF]

, 2010
We use a galaxy formation model to study the nature and evolution of emission line galaxies. In particular, we focus on the properties of Ly-alpha and H-alpha emitters, due to their many cosmological applications being considered for current and ...

Cross‐Referencing Astronaut‐Observed Lunar Impact Flashes With Seismic Data—Lessons From Apollo for Artemis

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract During their orbits of the Moon in 1972, Apollo astronauts reported three impact flashes, associated with meteoroids striking the surface and vaporizing. We examined data from the Apollo seismic network to investigate whether these flashes produced detectable moonquakes whose locations and timing could be independently validated.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

The Lukewarm Frontier: Some Cosmological Consequences of 'Low Energy' Physics [PDF]

, 2010
In this thesis, we present four projects featuring low characteristic energy scales relative to the scales relevant for supersymmetric dark matter production or inflation. We present a telescope search for decaying relic axions in the 3 − 8 eV mass range.

Plasma Properties at the Orbits of Ganymede and Callisto: Survey of Juno Data

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The space environment around the Galilean moons is important for understanding the interaction of the magnetospheric plasma with their magnetosphere (in the singular case of Ganymede), their atmospheres and surfaces. Juno's orbital evolution brought the spacecraft close to the orbits of Ganymede and Callisto on multiple occasions over several ...

Black Hole Mergers and Their Electromagnetic Counterparts [PDF]

, 2011
Over the past ten years it has become increasingly clear that most, if not all, galaxies have super-massive black holes lurking in their cores. The implications for this are large as they not only have significant effects on the host galaxies, far beyond
