Dark matter annihilation into leptons through gravity portals

Journal of High Energy Physics, 2021
Dark matter (DM) constitutes 85% of the matter in the Universe. However, its specific particle property is still unclear. The fundamentals of DM particles subject to gravitational interaction, and that the lepton excess in cosmic rays may originate from ...

Group theoretic approach to fermion production

Journal of High Energy Physics, 2019
We propose a universal group theoretic description of the fermion production through any type of interaction to scalar or pseudo-scalar. Our group theoretic approach relies on the group SU(2) × U(1), corresponding to the freedom in choosing ...

A model of interacting dark matter and dark radiation for H0 and σ 8 tensions

Journal of High Energy Physics, 2021
We present a model describing the dark sector (DS) featured by two interactions remaining efficient until late times in the matter-dominated era after recombination: the interaction among dark radiations (DR), and the interaction between a small fraction

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Kelvin–Helmholtz Spectral Redistribution by Flow and Density Structure at the Dusk Dayside Magnetopause

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract We study the development of the Kelvin‐Helmholtz instability (KHI) along the dusk dayside Earth's magnetopause with and without the presence of enhanced plasma density at the shear interface. Using three‐dimensional MAGE global simulations, we establish general KHI growth rate diagrams, which depend sensitively on the transverse profiles of ...

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 ...

Distal Rays and Secondary Craters of the Tycho Impact Event Revealed Through Deep Learning

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The nature of secondary impact craters is a matter of ongoing debate, with important implications for understanding the impact cratering process, and for calibration of crater chronology. Rays generated by primary impact craters are characterized by secondary craters, providing identifiable terrains to study the size, morphology and clustering

Global fits of axion-like particles to XENON1T and astrophysical data

Journal of High Energy Physics, 2021
The excess of electron recoil events seen by the XENON1T experiment has been interpreted as a potential signal of axion-like particles (ALPs), either produced in the Sun, or constituting part of the dark matter halo of the Milky Way.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...
