Περίληψη

Finding the sources of Ultra-High-Energy Cosmic Rays (the most energetic particles in our Universe) still remains a great challenge. Their discovery will not only give us insight as to what mechanism (cosmic accelerator) could possibly accelerate these particles to energies up to 1020 eV, but will also possibly reveal new particle physics at these highest energies. One of the main difficulties in locating the sources of Ultra-High-Energy Cosmic Rays (UHECRs) is that they get deflected by the Galactic magnetic field as they travel towards the Earth, coupled with the fact that our knowledge of the 3-dimensional structure of the Galactic magnetic field is limited. Once the 3-d properties of the Galactic magnetic field are better understood, the trajectories of UHECRs through the galaxies can be reconstructed and followed backwards (backtracking), to ”correct” the observed arrival directions of UHECRs, bringing them closer to their sources. In this work, we study how to treat such corrected arrival directions. In particular, we seek to understand when a doublet (two events with nearby arrival directions) are consistent with coming from the same source, and when two or more events are consistent with coming from some specific, well-motivated candidate source.
