Quasi‐Constant Time Gap in Multiple Rings of Elves

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

THE IMPACT OF SUZAKU MEASUREMENTS ON ASTROPARTICLE PHYSICS

Acta Polytechnica, 2013
Results from the Suzaku X-ray broad-band observations of clusters of galaxies are summarized. Aiming at understanding the physics of gas heating/particle acceleration and the cluster dynamical evolution, we search for non-thermal hard X-ray emission from

Thunderstorm Charge Distribution Determination Using Cosmic Rays Induced Air Showers and Lightning Imaging at LOFAR

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The LOw Frequency ARray (LOFAR) radio telescope possesses the unique capability to measure ultra‐high energy cosmic rays as well as image lightning discharges. This study presents a comparison between the inferred thunderstorm charge structures derived from cosmic‐ray measurements and from lightning flashes.

The Plasma Proton Environment Within Saturn's F‐G Ring Gap as Observed by the Cassini Plasma Spectrometer Ion Mass Spectrometer During Saturn Orbit Insertion

Journal of Geophysical Research: Space Physics, Volume 130, Issue 2, February 2025.
Abstract We report on the detection of protons and the potential detection of H2+ between Saturn's F and G rings based on Cassini Plasma Spectrometer (CAPS) Ion Mass Spectrometer (IMS) time‐of‐flight (TOF) composition measurements acquired during Saturn Orbit Insertion (SOI) outbound pass. The range in dipole L shell is 2.3 < L < 2.8.

Measurement of radio emission from extensive air showers

, 2009
A new promising development in astroparticle physics is to measure the radio emission from extensive air showers. The particles in the cascade emit synchrotron radiation (30 - 90 MHz) which is detected with arrays of dipole antennas.

Multi‐Photon 3D Laser Micro‐Printed Plastic Scintillators for Applications in Low‐Energy Particle Physics

Advanced Functional Materials, Volume 35, Issue 2, January 9, 2025.
Many modern detector systems require structured scintillators in combination with photo‐detectors. This requirement can be fulfilled by 3D printing plastic scintillators which becomes more and more relevant. However, the resolution and surface quality of 1‐photon‐based 3D printing techniques are not sufficient for many applications.

Gravitational wave signatures from domain wall and strong first-order phase transitions in a two complex scalar extension of the Standard Model

Journal of High Energy Physics, 2021
We consider a simple extension of Standard Model by adding two complex singlet scalars with a U(1) symmetry. A discrete Z 2 × Z 2 ′ $$ {\mathcal{Z}}_2\times {\mathcal{Z}}_2^{\prime } $$ symmetry is imposed in the model and the added scalars acquire a non

Models with two Higgs doublets and a light pseudoscalar: A portal to dark matter and the possible (g−2)μ excess

Physics Letters B, 2022
In the context of a two-Higgs doublet model, supplemented by an additional light pseudoscalar Higgs boson and a stable isosinglet fermion, we consider the possibility of addressing simultaneously the discrepancy from the standard expectation of the ...
