Astrophysics and Astroparticles

The course completes the program of the major course Particles, Nuclei and Universe on astrophysics by an introduction on our Galaxy, the interstellar matter, star formation and planetary systems. Basic knowledge on compact objects, large-scale structures and magnetic fields are provided. Furthermore, the course introduces concepts related in particular to Astroparticle Physics: cosmic ray acceleration and propagation. An overview of various detection techniques of cosmic radiations and particles will be provided.
