Description

This course is an introduction to astroparticle physics (cosmic gas pedals, gamma rays, multi-messengers, experimental techniques, ...).

The course builds on the knowledge acquired in L3 to offer students a brief introduction to astroparticle physics. After a description of the general context, two examples of detectors in gamma-ray astronomy will be detailed, followed by an introduction to the physics of multi-messenger astrophysics (in particular via the detection of gravitational waves). The course will then address the physics of cosmic rays (CR), the problem of acceleration and propagation of CRs and the hypothesis of Supernova remnants as galactic gas pedals of CRs (description of the first order Fermi acceleration mechanism).

The course will conclude with a description of the cosmological challenges of future large field surveys on the ground and in space (LSST and Euclid in particular).
