Laboratory presentation

DAp (Astrophysics Division), a joint research unit within Irfu, is an internationally recognized major space laboratory.
It is heavily involved in numerous research projects covering the fields of astrophysics, instrumentation and numerical simulation. In particular, the laboratory realizes and exploits instruments installed on large telescopes or on-board in space (in low orbit, at Lagrangian points, around Saturn, ...) within the framework of the space or bilateral missions. The DAp also has access to the largest computers in Europe for its numerical simulations based on the multi-scale analysis (from the scale of planets to galaxy clusters) which make it possible to trace the structure of the universe over time. The laboratory also relies on advanced technical expertise in the field of system architecture, quality, electronics and spatial spectro-imagers.
