## Abstract in another language

We construct a model for the Milky Way where the interstellar medium (ISM) is equipped with self-consistent dynamics. In simulations a spiral structure emerges from this model that is almost identical with the one in the Milky Way's ISM. Further, the Jeans instability offers an explanation for the observed velocity dispersion of atomic hydrogen in the ISM; this instability vanishes from our model if we choose a velocity dispersion just above the observed one. Surprisingly, our model gets along completely without dark matter. The 'missing mass' distributes uniformly over the baryonic components making it possible to explain the occurring mass gap.
