Learning Objectives

The course is aimed to introduce the students to the fundamental concepts of astroparticle physics. Both experimental and phenomenological aspects will be treated. The link between particle physics, astrophysics and cosmology will be critically analysed. The student will understand the importance to investigate different messengers (neutrinos, cosmic rays, gamma rays) to achieve a global view of our universe and to understand its evolution. The student will acquire a critical knowledge about the most important and up-to-date topics in the field like the origin of dark matter and dark energy, the properties of neutrinos and cosmic rays, as well as the most innovative detection techniques.
