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…
The Scintillator Surface Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
Data collected so far by the Pierre Auger Observatory have enabled major advances in ultra-high energy cosmic ray physics and demonstrated that improved determination of masses of…
Scaler rates from the Pierre Auger Observatory: a new proxy of solar activity
The Pierre Auger Collaboration, I. Bizzarri, C. Dionese +1
The modulation of low-energy galactic cosmic rays reflects interplanetary magnetic field variations and can provide useful information on solar activity. An array of ground-surface…
