Abstract
The Pierre Auger Observatory is the World's largest detector of cosmic rays with energies between $10^{17.5}\:\mathrm{eV}$ and $10^{20}\:\mathrm{eV}$. Composed of a surface detector, formed by an array of 1660 \u{C}erenkov water detectors arranged on an area of $3000\:mathrm{km^{2}}$, and 5 fluorescence detectors, the Pierre Auger Observatory has among its main objectives, to determine th…
