Description
Abstract:
Thanks to the large amount of data delivered by the Gaia satellite and their excellent precision, in the last three years we have experienced a vertiginous progress in the studies of our Galaxy. I will talk about the discovery of unexpected structures in the Milky Way phase-space such as the Gaia phase spiral and ridges in the disc planar velocities. I will show how these findings are helping us to unravel a complex Milky Way that is being perturbed both by internal mechanisms such as the bar and the spiral arms, and the interaction with its companion galaxies such as Sagittarius.
