In a recent review article current searches for ultra-high-energy (UHE) photons at the Pierre Auger Observatory were summarized.
Scientific Highlights
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.
Dark matter could have been created in the primordial universe from gravitational interactions between all forms of matter.
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".
