Galaxies in a LCDM universe: the vital role of baryon physics

The standard cold-dark matter (CDM) model for galaxy formation is a powerful tool to describe the large scale structure of the Universe, suffering however from several issues on small, galactic scales.
To overcome such problems baryonic physics processes should be considered as well in galaxy formation models. I will review the importance of gas outflows in solving several of the small-scale issues. I will talk in particular about the recently discovered Ultra-Diffuse galaxies, which are a natural outcome of LCDM haloes in which dark matter and stellar cores are formed by such outflows.
