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…

Precision cross-sections for advancing cosmic-ray physics and other applications: a comprehensive programme for the next decade

D. Maurin, L. Audouin, E. Berti +32

Cosmic-ray physics in the GeV-to-TeV energy range has entered a precision era thanks to recent data from space-based experiments. However, the poor knowledge of nuclear reactions,…

Deciphering the Electron Spectral Hardening in AMS-02

Carmelo Evoli

We analyze the electron cosmic-ray spectrum from AMS-02, focusing on the spectral hardening around 42 GeV. Our findings confirm that this feature is intrinsic to the primary electr…

A Critical Examination of the Nested Leaky Box Model for Galactic Cosmic Ray Transport

Benedikt Schroer, Carmelo Evoli, Pasquale Blasi

We revisit the predictions of the nested leaky box model in detail, in terms of both primary cosmic-ray spectra, spectra of stable and unstable nuclei and antimatter production (po…

A search for the anomalous events detected by ANITA using the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +374

A dedicated search for upward-going air showers at zenith angles exceeding and energies EeV has been performed using the Fluorescence Detector of the Pierre Aug…

Search for a diffuse flux of photons with energies above tens of PeV at the Pierre Auger Observatory

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

Diffuse photons of energy above 0.1 PeV, produced through the interactions between cosmic rays and either interstellar matter or background radiation fields, are powerful tracers o…
