Bounds on Lorentz invariance violation from muon fluctuations at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357
Quantum gravity theories often modify spacetime symmetries. In particular, Lorentz invariance may be violated when approaching the Planck scale. Although the scales at which intera…
POEMMA-Balloon with Radio: A multi-messenger, multi-detector balloon payload
J. Adams, J. Alfaro, D. Allard +123
A review of the current status of the field of Ultra-High-Energy Cosmic Ray (UHECR) including a summary of remaining open questions was presented in the white paper "Ultra-High Ene…
Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357
Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…
Long-term calibration and validation of stability of the Auger Engineering Radio Array using the diffuse Galactic radio emission
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +356
The Auger Engineering Radio Array (AERA) measures radio emission from high-energy extensive air showers. Consisting of 153 autonomous radio-detector stations spread over \,km$^…
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,…
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…
