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 ...

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.

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.

Astroparticle Physics in Hyper-Kamiokande [PDF]

Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2017
Hyper-Kamiokande is a proposed next-generation general purpose neutrino detection experiment. It comprises an underground water Cherenkov detector that will be more than 8 times as large as the highly successful Super-Kamiokande and use significantly improved photodetectors with the same 40 % photocoverage.

Astroparticle Physics — A personal outlook [PDF]

Nuclear Physics B - Proceedings Supplements, 1996
At the request of the organizers, this talk surveys some of the hot topics discussed at this meeting, giving my {\it subjective views} on them. Subjects covered include the present age and Hubble expansion rate of the Universe - {\it inflation theorists need not yet abandon $Ω= 1$}, theories of structure formation in the light of COBE and other data - {
