Long-term calibration and validation of stability of the Auger Engineering Radio Array using the diffuse Galactic radio emission
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +356
The Auger Engineering Radio Array (AERA) measures radio emission from high-energy extensive air showers. Consisting of 153 autonomous radio-detector stations spread over \,km$^…
Quasi-constant time gap in multiple rings of elves
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +359
We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To…
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…
