Spectral Analysis of Flickering Gamma‐Ray Flashes Observed During the ALOFT 2023 Campaign

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract We examine a newly discovered category of high‐energy radiation events called flickering gamma‐ray flashes (FGF) detected during the airborne lightning observatory for FEGS and TGFs campaign in July 2023. These FGFs are characterized by highly pulsating gamma‐ray emissions that have no detectable concurrent optical or radio signals (Ostgaard ...

Solar neutrinos and leptonic spin forces

Journal of High Energy Physics
We quantify the effects of light spin-zero particles with pseudoscalar couplings to leptons and scalar couplings to nucleons on the evolution of solar neutrinos. In this scenario the matter potential sourced by the nucleons in the Sun’s matter gives rise

A direct detection view of the neutrino NSI landscape

Journal of High Energy Physics, 2023
In this article, we study the potential of direct detection experiments to explore the parameter space of general non-standard neutrino interactions (NSI) via solar neutrino scattering.

Linking solar and long baseline terrestrial neutrino experiments [PDF]

, 1999
We show that in the framework of three light neutrino species with hierarchical masses and assuming no fine tuning between the entries of the neutrino mass matrix, one can use the solar neutrino data to obtain information on the element $U_{e3}$ of the ...

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Status of direct determination of solar neutrino fluxes after Borexino

Journal of High Energy Physics
We determine the solar neutrino fluxes from the global analysis of the most up-to-date terrestrial and solar neutrino data including the final results of the three phases of Borexino.

Solar neutrino scattering with electron into massive sterile neutrino

Physics Letters B, 2020
The recent Xenon1T excess can be explained by solar neutrino scattering with electron via a light mediator, either scalar or vector, in addition to many other explanations from the dark sector.

Constraining super-light sterile neutrinos at Borexino and KamLAND

Journal of High Energy Physics, 2022
The presence of a super-light sterile neutrino can lead to a dip in the survival probability of solar neutrinos, and explain the suppression of the upturn in the low energy solar neutrino data.

Quantification of Perturbation to the Daytime Lower Ionosphere From a Gamma Ray Burst Using ELF Remote Sensing

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract On 9 October 2022, a powerful gamma ray burst (GRB), GRB221009A, caused significant changes in the electron density of the lower ionosphere, as evidenced by VLF (3–30 kHz) radio wave observations. However, GRB221009A did not yield any observable signatures at the Schumann resonances (∼8, ∼14 Hz), which are also sensitive to the lower ...

Short review on solar neutrinos experiments and search for sterile neutrinos with solar neutrino detectors

EPJ Web of Conferences, 2015
The spectroscopy of solar neutrinos is now entering the precision era, after a golden age which has led to the discovery of neutrino oscillations and the MSW effect.
