Has telescope array discovered electroweak monopole?

Physics Letters B
We propose the ultra high energy cosmic ray recently detected by Telescope Array to be the electroweak monopole, and present theoretical arguments which support this.

Modified Temperature–Redshift Relation and Ultra-high-energy Cosmic Ray Propagation

The Astrophysical Journal
We reexamine the interactions of ultra-high-energy cosmic rays (UHECRs) with photons from the cosmic microwave background (CMB) under a changed, locally nonlinear temperature–redshift relation T ( z ).

A Detectable Ultra-high-energy Cosmic-Ray Outburst from GRB 221009A

The Astrophysical Journal
Gamma-ray bursts (GRBs) have been proposed as one of the promising sources of ultra-high-energy cosmic rays (UHECRs), but observational evidence is still lacking.

The ATLAS Hadronic Physics Program and High Energy Cosmic Rays

EPJ Web of Conferences, 2013
The various aspects of the current and future ATLAS programs to explore hadronic physics, including diffraction and forward physic are discussed The emphasis is p laced on those results and future plans that have particular relevance for high-energy, and

Anisotropy studies with the Pierre Auger Observatory

EPJ Web of Conferences, 2013
Recent results from the Pierre Auger Observatory about anisotropies in the arrival directions of ultra-high energy cosmic rays are reported. In the EeV energy range, we present the results of a search for a large scale dipolar anisotropy pattern.

Recent Ultra High Energy neutrino bounds and multimessenger observations with the Pierre Auger Observatory

EPJ Web of Conferences, 2017
The overall picture of the highest energy particles produced in the Universe is changing because of measurements made with the Pierre Auger Observatory. Composition studies of cosmic rays point towards an unexpected mixed composition of intermediate mass
