Advanced ISM models for galaxy formation simulations

Hydrodynamical simulations have enormously advanced our theoretical understanding of the evolution galaxies. Indeed, the current generation of simulations has been increasingly successful at producing simulated galaxies that look very much alike to the ones populating the real Universe. Notwithstanding this undeniable success, galaxy formation models included in state of the art simulations often adopt very crude approximations -- due to resolution limitations -- that can severely limit their predictive power. In this talk, I will briefly present ongoing efforts that go in the direction of improving the physical description of key processes that shape the evolution of galaxies, particularly for what concerns stellar feedback and ISM properties. This often entails connecting processes acting over a vast range of scales, a formidable task that is however necessary to draw coherent physical picture of galaxy formation.
