Measuring the muon content of inclined air showers using AERA and the water-Cherenkov detectors of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360

We present a novel approach for assessing the muon content of air showers with large zenith angles on a combined analysis of their radio emission and particle footprint. We use the…

Scaler data from the Pierre Auger Observatory as a proxy of solar activity

C. Taricco, I. Bizzarri, C. Dionese +1

Solar activity variations strongly impact the modulation of the flux of low-energy Galactic Cosmic Rays (GCRs) reaching the Earth. The secondary particles, which originate from the…

Detection of ultra-high-energy cosmic rays in the southern hemisphere with FAST: data acquisition and preliminary results

Jakub Kmec, Petr Boril, Fraser Bradfield +29

Ultra-high-energy cosmic rays (UHECRs) remain one of the greatest mysteries in astroparticle physics. The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a next-ge…

Progress towards stereo observation of ultra-high-energy cosmic rays with Fluorescence detector Array of Single-pixel Telescopes

Shunsuke Sakurai, Justin Albury, Jose Bellido +33

Ultra-high-energy cosmic rays (UHECRs) are the most energetic particles ever detected. Cosmic rays that achieve the highest energies are rare, and their flux at Earth is extremely…

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…
