Design, upgrade and characterization of the silicon photomultiplier front-end for the AMIGA detector 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. This new design is destined to be used in the production phase of the AMIGA project. Compared to our previous prototype with MPPMT (Multi-Pixel Photomultiplier Tubes), the new electronics shows a higher performance, higher efficiency and lower power consumption.

Most precise measurement of the cosmic-ray energy spectrum at ultra-high energies

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). The data set consists on 215,030 events with zenith angles below 60° and energies larger than 2.5x1018 eV.

Cosmic-ray anisotropies in right ascension measured by the Pierre Auger Observatory

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.

Directional sensitivity of the Pierre Auger Observatory to sources of UHE neutrinos

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.
