The ROME/REA microlensing survey: Three years of Galactic bulge observations

Yiannis Tsapras , ARI

The ROME/REA project (2017-2020) aimed to discover extrasolar planets by regularly monitoringmillions of stars in the Galactic bulge and looking for ongoing microlensing events. From April to Septembereach year, when the Galactic bulge was visible from the Southern hemisphere, the robotic telescopes of theLas Cumbres Observatory were used to observe a total area of about 4 square degrees in the sky in threedifferent bands. An automated process assessed ongoing microlensing events in real time for their sensitivityto planetary signals and additional observations were requested to characterize signals of particular scientificinterest. Our final catalog of stars contains more than 4 million individual sources. As we prepare for our firstpublic data release, I will present some of the results, talk about the data products we will soon be releasingand describe our current work and plans for the future.
