Hidden structures in the UHE sky: unveiling potential cosmic-ray sources via spectral signatures
Mateus Zeferino Rennó, Cainã de Oliveira
The search for the origin of ultrahigh-energy cosmic rays (UHECRs) typically relies on identifying directional excesses in the particle flux. While this approach is well establishe…

Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346
Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…

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…
