We propose to studyt Lorentz invariance in the context of astroparticle physics. The most energetic particles we can study are produced in astrophysical enviroments and detected on earth by dedicated experiments. These particles represents an extraordinary oportunity to study Lorentz invariance due to its extreme energy and large distance of the source. Cosmic rays are an important source of information because they are produced in extreme sites of the universe and travels long distances until earth. In the production and on the way to earth, quantum-gravity effects can accumulate and residual manifestations can be detected by the Pierre Auger Observatory (E ~10^ {20} eV) or by the CTA Observatory (E ~ 10^ {12} eV). In this master project, the student will approach these questions in two contexts: a) exploring the energy spectrum measured by the Pierre Auger Observatory and b) studying the temporal dispersion of the signal to be measured by the CTA Observatory.
