Linking small scales structures with global properties of the Milky Way

Abstract
The advent of the Gaia data, in particular its 6D sample, has finally allowed us to precisely characterise the kinematic space throughout a significant portion of the Milky Way disc(s). In doing so, we are now able to quantify the properties of the different kinematic substructures and follow their changes with Galactocentric radius and azimuth. I will present the latest advances in this topic, discuss its implications on the global properties of the Galaxy and its history, and show how we can use this information to constrain the Milky Way gravitational potential.
