Abstract

The production of ultra high energetic particles in the Universe is one of the most imprtant mysteries in modern science. The acceleration mechanisms in astrophysical sources are not known and recent results points to the need of a multi-mensager approach to help in understanding this puzzle. The interpretation of the data depends on our knowledge of the fundamental interactions in a energy range beyond the reach of man-made accelerators. Therefore, astroparticle physics is an unique research field in which fundamental astrophysics and particles physics play a important role. In this project, we will study the possibility to detect ou set limits on the Lorentz invariance using the propagation of particles in the Universe and we will study the possibility to detect dark matter in indirect measurement of gamma-ray flux. Part of the work to be done in the PhD is a extension of the master dissertatino of the student and the our effort is inserted in the Pierre Auger and CTA Observatory framework. (AU)
