Abstract:
Galaxies are the largest well organized systems in the Universe, which provide through surprisingly complex interactions between micro- and macro-physics the suitable conditions for the formation of stars and planets. Although many phenomena taking place in galaxies are increasingly better understood, other aspects, such as dark matter, remain mysterious and represent serious physics challenges. The aim of this presentation is to expose for non-experts with some physics background our updated understanding about galaxies that has been achieved with the current observational and computational technical advances. Remaining problems will also be discussed.
