In astrophysics and astrometry, the focus is on determining the positions of celestial and artificial bodies through observations with high precision to improve the dynamic parameters of gravitational systems. For example, deducing elements of internal composition allows scientists to trace back the formation of these systems and the evolution of life in the Universe. Currently, this field is oriented towards digitizing old photographic plates to enhance ephemerides (NAROO project – see below), notably improving predictions of impact probabilities of near-Earth asteroids, some of which are classified as PHAs (Potentially Hazardous Asteroids). These efforts are carried out jointly with IMCCE.
Part of the team is dedicated to advising and mentoring student technical associations on space-related projects.
Finally, two researchers focus on fundamental issues in particle physics and nuclear physics.
