In a recent publication, the Pierre Auger Collaboration has presented the design of the AMIGA Data Acquisition System
First measurement of the fluctuations in the number of muons in air showers at ultra-high energies.
Enhanced measurements of muons in air showers will allow improved estimations of the chemical composition of cosmic rays at the Pierre Auger Observatory.
In a recent publication, the Pierre Auger Collaboration has presented the design and performance tests of the new front-end with silicon photomultiplier (SiPM) for the AMIGA detectors.
Recently, the Pierre Auger Collaboration has presented the most precise measurement of the cosmic-ray (CR) energy spectrum at ultra-high energies using the events recorded over more than 14 years by the surface detector (SD).
In a recent publication, the Pierre Auger Observatory has presented measurements of the large-scale cosmic-ray (CR) anisotropies in right ascension, using data collected by the surface detector array over more than 14 years, up to 31st August 2018. The dataset covers the energy range from ~0.03 EeV up to the highest detected energies.
