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…

Search for active-sterile neutrino transitions using Pierre Auger Observatory data

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348

We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…

Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347

Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…

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…

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…

Large-scale cosmic ray anisotropies with 19 years of data from the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +355

Results are presented for the measurement of large-scale anisotropies in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory during 19…
