Impact of uncertainties on the cosmic optical and infrared backgrounds on the propagation of astroparticles

Lucas Gréaux, Antonio Condorelli, Leonel Morejon +2

When propagating through the universe, gamma rays at very-high energy (VHE, E > 100 GeV) and ultra-high energy cosmic rays (UHECRs, E > 1 EeV) can interact with the optical, infrar…

Blazars as a Potential Origin of the KM3-230213A Event

The KM3NeT Collaboration

The KM3NeT collaboration has reported the detection of the highest energy neutrino event observed to date. The energy of the event is of the order of 220 PeV hinting towards a neut…

Quasi-constant time gap in multiple rings of elves

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +359

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…

Multi-messenger constraints on transient accelerators of ultra-high energy cosmic rays

Antonio Condorelli, Jonathan Biteau, Olivier Deligny +1

The origin of ultra-high-energy cosmic rays (UHECRs) remains an open questions in astrophysics. We explore two primary scenarios for the distribution of UHECR sources, assuming tha…

Measuring the muon content of inclined air showers using AERA and the water-Cherenkov detectors of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360

We present a novel approach for assessing the muon content of air showers with large zenith angles on a combined analysis of their radio emission and particle footprint. We use the…

Scaler rates from the Pierre Auger Observatory: a new proxy of solar activity

The Pierre Auger Collaboration, I. Bizzarri, C. Dionese +1

The modulation of low-energy galactic cosmic rays reflects interplanetary magnetic field variations and can provide useful information on solar activity. An array of ground-surface…
