This looks like the most natural question regarding ultra-high energy cosmic rays, but it’s also one of the hardest ones to be answered.
Scientific Highlights
The latest data of the Pierre Auger Observatory constrains scenarios of super-heavy particle relics.
The possibility of some level of Lorentz invariance violation at very-high energies has been proposed in the context of theories beyond the Standard Model, quantum gravity and string theory.
The Pierre Auger Collaboration recently introduced a deep-learning-based method to reconstruct the depth of maximum air shower profiles
Recently, the Pierre Auger collaboration presented a measurement of the cosmic ray spectrum near the feature known as the "second knee".
The Pierre Auger Collaboration has published a method to predict the component due to muons of the signals recorded by the water-Cherenkov detectors that comprise the Surface Detector (SD) of The Pierre Auger Observatory.
