If you have a question about this talk, please contact Amaury Triaud.

In this talk I will review my group’s efforts to study the Galaxy, exploiting in a unique way phenomena related to compact objects. I will show how we are finding hypervelocity stars in the Gaia catalogue with machine learning algorithms and modelling them to simultaneously constrain the dark matter halo and the Galactic centre’s stellar population. In particular, I will present results from Gaia’s first (September 2016) and second (April 2018) data releases, and our forecasting for the final one (2022). Complementary, I will show how data from the Laser Interferometry Space Antenna (LISA) can be used to pin down the distribution and mass of the baryonic matter content.
