Radio Measurements of the Depth of Air-Shower Maximum at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +372
The Auger Engineering Radio Array (AERA), part of the Pierre Auger Observatory, is currently the largest array of radio antenna stations deployed for the detection of cosmic rays,…
Ground observations of a space laser for the assessment of its in-orbit performance
The Pierre Auger Collaboration, O. Lux, I. Krisch +380
The wind mission Aeolus of the European Space Agency was a groundbreaking achievement for Earth observation. Between 2018 and 2023, the space-borne lidar instrument ALADIN onboard…
Search for active-sterile neutrino transitions using Pierre Auger Observatory data
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348
We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…
Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347
Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…
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…
The Energy Spectrum of Ultra-High Energy Cosmic Rays across Declinations to as measured at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360
The energy spectrum of cosmic rays above 2.5 EeV has been measured across the declination range using data from events accrued a…
