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