Hydrodynamical numerical simulations of galaxy formation provide important insights about the non-linear emergence of cosmic structures. Numerically, this problem requires a complicated mix of solvers for collisionless dynamics, magnetohydrodynamics and radiative transfer, in addition to long-range gravity. Physically, the problem lies in understanding the back reaction of small-scale physics close in to black holes and stars onto much larger cosmological scales. I will discuss a selection of current results in this field and highlight a few future directions, focusing on simulations of Milky Way-sized galaxies and the magnetic fields they contain.
