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 the second paper of a series of two devoted to the search for Ultra-High Energy (UHE) neutrinos at the Pierre Auger Observatory, the Pierre Auger Collaboration has addressed the sensitivity of the Surface Detector array (SD) to steady and transient point sources of UHE neutrinos as a function of declination.
This data-based method Improves the accuracy on the determination of the energy of cosmic rays with the Pierre Auger Observatory by 5%.
