Résumé

In fact, ultra-high-energy cosmic rays (UHECRs) represent the most
energetic particles in the universe, thus reaching energies over a million times
higher than man-made accelerators.However, even with decades of observations, their origins and acceleration mechanisms remain elusive. In virtue of
which, recent data from experiments such as, the Pierre Auger Observatory and
Telescope Array, have provided important insights, detecting a flux suppression
at the highest energies consistent with the GZK cutoff. Besides, this suggests an
extragalactic origin, though challenges remain in discriminating between galactic and extragalactic populations together with tracing arrival directions.In closing, upcoming detector upgrades and next-generation observatories aim to enhance precision and statistics, promising to unravel these astroparticle physics
mysteries.
