    1. Presentation of the conference

    - Scientific rationale

    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.

    This 3-day conference will bring together members of the community to discuss all aspects related to microlensing, including (but not limited to):

    • Astrometric microlensing
    • Interferometric microlensing
    • Detection of free-floating planets, exoplanets, brown dwarfs, stars and binaries, compact objects, including white dwarfs and black holes
    • Cold planet demographics (observational constraints and theory)
    • Stellar populations and their properties in the Milky Way (and other galaxies)
    • Search for electromagnetic signatures of gravitational-wave sources through microlensing.
    • Synergies between ground-based facilities and/or space missions (Gaia, Roman, Euclid, Rubin, ELTs, etc.)
    • Data mining, numerical tools and technique

    Our intention is to hold the conference in-person at the Institut d’Astrophysique de Paris (France). However, the conference will be broadcast live and virtual presentations will be accepted.

     Should the safety restrictions due to the COVID-19 prevent us from meeting in Paris, the conference will become fully virtual.
