Notional Geological Traverses, Station Activities, and Sample Collection on Mons Malapert, Lunar South Polar Region

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract The geology of a potential Artemis landing site on Mons Malapert is examined using remote sensing techniques and lessons learned from Apollo missions to the lunar surface. Orthomosaics, digital terrain models, illumination models, thermal conditions, crater size‐frequency distribution analyses, geomorphological mapping, spectral and ...

Global Structure of the Cislunar Magnetotail and Its Evolution During Substorms

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract So far, the structure and dynamics of the terrestrial magnetotail have largely been investigated within 31RE $31{R}_{E}$ (RE ${R}_{E}$ is the Earth's radius) because of the lack of in‐situ observations beyond that distance, as well as limitations of earlier empirical models.

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1441-1479, July 2025.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

A toy model based analysis on the effect of the Lee-Wick partners in the evolution of the early universe

, 2012
In the present article the thermodynamic results of the Lee-Wick partner infested universe have been applied in a toy model where there is one Lee-Wick partner to each of the standard model particle and more over the longitudinal degrees of freedom of ...

Extended Scenarios for Solar Radio Emissions With Downshifted Electron Beam Plasma Excitations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract First‐principle studies of radiative processes aimed at explaining the origin of type II and type III solar radio bursts raise questions on the implications of downshifted electron beam plasma excitations with frequency (slightly) below the plasma frequency ω≲ωpe $\left(\omega \lesssim {\omega }_{pe}\right)$ in the generation of radio ...

Inert scalar dark matter in an extra dimension inspired model

, 2014
In this paper we analyze a dark matter model inspired by theories with extra dimensions. The dark matter candidate corresponds to the first Kaluza-Klein mode of a real scalar added to the Standard Model.

Core‐Halo Correlations of Solar Wind Electrons and Temperature Anisotropy Instabilities

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract The properties of electrons in the heliospheric plasma are modulated by various factors, starting with the expansion and bimodal nature of the slow or fast solar wind, and continuing with the kinetic mechanisms of acceleration and energy exchange with small‐scale plasma waves.

Reconnection Onset in Overstretched Thin Current Sheets: PIC Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract Onset of reconnection in the magnetotail requires its current sheet (CS) to thin down to the thermal ion gyroradius (or thinner) to demagnetize ions (or even electrons) and to provide their Landau dissipation. However, in isotropic plasma models of the tail the ion‐scale CSs inflate too rapidly with the distance from Earth to remain ion‐scale ...

Cartographies of Clothing: On the Aesthetics and Practices of Property in Borderlands

PoLAR: Political and Legal Anthropology Review, Volume 48, Issue 1, May 2025.
ABSTRACT This article explores the symbolic and material role of clothing in shaping the aesthetics and practices of property among the Garos in the India‐Bangladesh borderlands. It argues that clothing functions as a mediator of territorial claims, transcending the legal frameworks of national and customary orders to offer alternative understandings ...
