Abstract: The exquisite astrometric dataset that Gaia DR3 offers to the scientific community makes the Large and Small Magellanic Clouds (LMC and SMC, respectively) a unique test laboratory to investigate and refine methodologies and models. The LMC is the first galaxy for which we can map a 3D velocity field of the complete galaxy (Jiménez-Arranz+23a) and endeavour dynamical studies in detail, such as the determination of the LMC bar pattern speed (Jiménez-Arranz+23c). For the first time, we can analyse the internal kinematics of an external galaxy and compare them with what theoretical models predict. This is fulfilled with KRATOS (Jimenez-Arranz+24, submitted), a suite of 28 pure N-body simulations of isolated and interacting LMC-like galaxies, to study the formation of substructures in their disc after the interaction with an SMC-mass galaxy, and a review of the planned scientific exploitation of these data.
