Speaker: Alfred Castro Ginard
Affiliation: Leiden Observatory, Leiden University


In this talk, I will present current efforts in mapping our own Milky Way. I will focus on how the wealth of data from the Gaia mission has redefined our understanding of the open cluster population, which is an excellent tracer of different Galactic structures. Particularly, I will review how machine learning methods have improved the detection of open clusters and the characterization of their properties. I will also go through how we use the newly defined open cluster census in a broader Galactic context, by using them as tracers of the Milky Way spiral arms. Finally, I will discuss how we can estimate the Gaia Survey Selection Function, and how completeness studies can be incorporated to have a better insight into our Milky Way.
