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,…

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…

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…

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…

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…

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
