Temporal Invariance Is an Illusion: Time-Dependent Influences of the Galactic Magnetic Field on UHECR Observations
Veronika Vašíčková, Leonel Morejón, Karl-Heinz Kampert
Understanding the origin of the Ultra-High-Energy Cosmic Rays (UHECRs) requires explaining the features of their energy spectrum, mass composition, and arrival directions. Current…
Depth of Maximum of Air-Shower Profiles above 10^17.7 eV Measured with the Fluorescence Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +358
We present measurements of the depth of shower maximum, Xmax, for cosmic-ray-induced extensive air showers recorded by the fluorescence detector of the Pierre Auger Observatory ove…
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…
The Pierre Auger Observatory: Contributions to the 39th International Cosmic Ray Conference (ICRC 2025)
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +352
The Pierre Auger Observatory, located in La Pampa Amarilla, Argentina, has been continuously acquiring data since 2004. It comprises a surface detector array covering 3,000 km…
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 at…
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…
Large-scale cosmic ray anisotropies with 19 years of data from the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +355
Results are presented for the measurement of large-scale anisotropies in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory during 19…
The distribution of ultra-high-energy cosmic rays along the supergalactic plane measured at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364
Ultra-high-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correla…
Search for photons above 10 eV by simultaneously measuring the atmospheric depth and the muon content of air showers at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364
The Pierre Auger Observatory is the most sensitive instrument to detect photons with energies above eV. It measures extensive air showers generated by ultra high energy c…
Measurement of the Depth of Maximum of Air-Shower Profiles with energies between and eV using the Surface Detector of the Pierre Auger Observatory and Deep Learning
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364
We report an investigation of the mass composition of cosmic rays with energies from 3 to 100 EeV (1 EeV= eV) using the distributions of the depth of shower maximum $X_\ma…
Impact of the Magnetic Horizon on the Interpretation of the Pierre Auger Observatory Spectrum and Composition Data
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364
The flux of ultra-high energy cosmic rays reaching Earth above the ankle energy (5 EeV) can be described as a mixture of nuclei injected by extragalactic sources with very hard spe…
