Description
The Sagittarius dwarf galaxy is without a doubt getting tidally disrupted by the Milky Way. Recent results from Gaia show that the Milky Way disc is far from equilibrium. Various works have shown that the interaction with Sagittarius can have a significant effect on unsettling the Galactic disc, resulting in many observed features like the Galactic warp, disc corrugation, spiral structure, phase space spirals, and even increased star-forming activity. However, many of these models assume an initial equilibrium, making the disc more susceptible to external perturbations. In my talk, I will present our recent, exciting results on how cosmologically evolved discs from the TNG50 simulation, which have never been in equilibrium, react to interactions similar to the one with Sagittarius.
