Microlensing events from all over the sky from Gaia

Łukasz Wyrzykowski  ✧  Astronomical Observatory, University of Warsaw, Poland

I will present the status of the microlensing search with the Gaia space mission through the Gaia Science Alerts channel and planned in the forthcoming Gaia Data Release 3 in 2022. The photometric events from Gaia will be supplemented by Gaia astrometric time-series, which will help measure Einstein Radius for many events and hence identify the nature of the lenses. The strongest astrometric signal is expected from massive lenses like black holes hence Gaia is going to revolutionize the field of black hole studies via microlensing. I will present the microlensing events from Gaia as well as the organization of their ground-based follow-up arranged via a network of tens of telescopes from around the globe.
