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…
Demonstrating Agreement between Radio and Fluorescence Measurements of the Depth of Maximum of Extensive Air Showers at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +372
We show, for the first time, radio measurements of the depth of shower maximum () of air showers induced by cosmic rays that are compared to measurements of the estab…
Identification of low energy neutral and charged cosmic ray events in large wide field observatories
L Apolinário, P. Assis, P. Brogueira +5
The lower energy thresholds of large wide-field gamma-ray observatories are often determined by their capability to deal with the very low-energy cosmic ray background. In fact, in…
Discriminating sub-TeV gamma and hadron-induced showers through their footprints
R. Conceição, B. S. González, A. Guillén +2
Gamma/hadron discrimination in ground-based gamma-ray observatories at the sub-TeV energy range is challenging as traditional muon-based methods become less effective at lower ener…
A search for the anomalous events detected by ANITA using the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +374
A dedicated search for upward-going air showers at zenith angles exceeding and energies EeV has been performed using the Fluorescence Detector of the Pierre Aug…
