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

open access: yesGeophysical 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 ...

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

open access: yesEarth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

FeCu/MWCNT Nanocomposite with a Broad Microwave Absorption Band and Highly Reduced Radar Cross Section and Farfield

open access: yesAdvanced Electronic Materials, Volume 11, Issue 15, September 18, 2025.
FeCu bimetallic nanoparticles were synthesized using coprecipitation method. FeCu bimetallic nanoparticles decorated onto the MWCNT's sidewall with different weight ratios to produce novel FeCu/MWCNT nanocomposites. The results showed that a thin nanocomposite exhibited a broad absorption band with coverage of entire frequency bands.

Detecting LHC neutrinos at surface level

open access: yesJournal of High Energy Physics
The first direct detection of neutrinos at the LHC not only marks the beginning of a novel collider neutrino program at CERN but also motivates considering additional neutrino detectors to fully exploit the associated physics potential.

Study on the Neutrino Oscillation with a Next Generation Medium-Baseline Reactor Experiment

open access: yesAdvances in High Energy Physics, 2014
For over fifty years, reactor experiments have played an important role in neutrino physics, in both discoveries and precision measurements. One of the methods to verify the existence of neutrino is the observation of neutrino oscillation phenomena ...

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

open access: yesAstronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...
