Division of accelerators, cryogenics and magnetism

Today our Universe is made up of stars, galaxies, clusters of galaxies but also huge voids. Yet when it was born over 13 billion years ago, matter was evenly distributed.

To understand the physical mechanisms responsible for this scenario, we need to trace the history of galaxies and their clustering by combining the three pillars which are observations, theoretical data modelling and numerical simulations.

This synergy covers a wide range of spatial scales and physical processes :

• from the physics of the interstellar medium to large-scale cosmological structures and wavelength domains;
• from far infrared to X-rays.
