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…

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,…

Likelihood-based reconstruction of muon lateral distribution function using combined integrator and binary detector modes

A. D. Supanitsky, D. Ravignani, V. V. Kizakke Covilakam

The origin of ultra-high-energy cosmic rays, with energies eV, remains unknown. Among the key observables used to investigate their nature are the energy spectrum,…

Search for UHE neutrinos from GRBs with the Pierre Auger Observatory

Yago Lema-Capeans

We report on the search for ultra-high-energy neutrinos from the prompt emission of gamma-ray bursts (GRBs) using Surface Detector (SD) data from Phase I of the Pierre Auger Observ…

Updated comparison of the UHECR energy spectra measured by the Pierre Auger Observatory and the Telescope Array

Douglas R. Bergman, Toshihiro Fujii, Kozo Fujisue +8

The Pierre Auger and Telescope Array joint Working Group on the UHECR energy spectrum was established in 2012 to analyze energy scale uncertainties in both experiments and to in ve…
