Le laboratoire héberge régulièrement des colloques et ateliers focalisant sur un sujet particulier
parmi les thématiques et projets du laboratoire.
Ces rencontres durent quelques jours et sont destinées à une audience professionnelle.
Gravitational microlensing has been used for decades as a tool to probe the content of our galaxy, explore its structure and properties. For example, microlensing surveys have enabled the study of the cold exoplanet populations orbiting at the birthplace of giant planets all the way to the Galactic center, thus providing insights on the Galactic distribution of exoplanets and strong constraints for the models of planet formation and evolution. Microlensing has also become a source of constraints for models of the Milky Way, the initial mass function, and for the existence of primordial black holes. Yet the power of microlensing probes has not yet been fully realized and has the potential to expand our knowledge of the frequency and mass-function of exoplanets, brown dwarfs, and compact objects, including black holes and white dwarfs in the Milky Way. New facilities and techniques are unlocking this potential, including the photometric and astrometric capabilities of HST, Gaia, ground-based adaptive optics systems, interferometry, JWST, Rubin Observatory, and the Nancy Grace Roman Space Telescope. The goal of this conference is to bring together members of the community to discuss all aspects related to microlensing.
