Title: DYNAMICAL INFLUENCE OF DWARF GALAXIES AND INTERNAL PERTURBATIONS ON THE CHEMODYNAMICS OF THE MILKY WAY DISK
Description: The candidate will model recently discovered phase-space structures in the thin/thick disk Milky Way stellar system and analysed them as being produced both by pure internal dynamical excitations (bar and spirals) and by dynamical perturbations induced by the passage of dwarf galaxies such as the one of Sagittarius. We aim to unveil a top-down chemodynamical scenario for the formation and evolution of such structures combining both the unprecedented multi-dimensional Big Data provided by ongoing surveys (GAIA-DR3, WEAVE, 4MOST) and the novel and realistic MW analogues simulations developed in the project of DC07. The new codes inspired on the algorithms for deep learning (DL) and AI techniques for multi-modal data sources developed in the project of DC04 will be adapted and readjusted to unveil the correlations between the intricate dynamical agents acting on the system and the observed complex structures in the n-dimensional space of the observables (position, velocities, chemical abundances, and ages). Novel simulations boosting the required spatial and temporal resolution will allow DC06 to create a new dynamical framework. This will be used to develop a unique scenario of the young and perturbed MW disk highlighted by the Phase Spirals and the classical large-scale mechanisms of migration, heating and/or excitation of vertical breathing on each of the stellar components of the Galactic disk.
Secondment are planned at RUG to work with Bunte on algorithms for Deep Learning applied to Galactic disk Gaia/WEAVE data, and at AVS to work with Salata on massive data processing technology in astronomy and Earth science.
