In this seminar I will discuss the ongoing effort in modelling the formation of extended spiral galaxies like the Milky Way.
I will review the advances made in the past few years within the galaxy simulation community, with an emphasis on the coupling between feedback from individual massive stars and the interstellar medium.
I will present new results from the "VINTERGATAN project" on the emerging chemo-dynamical structure of simulated galaxies, and outline why these may hold the promise of unravelling the formation of the Milky Way.
