Arguably two of the most important questions in Astrophysics today are: what is the Universe made of? and, how do galaxies form and evolve? Quite astonishingly we know only the properties of < 5% of the mass in the Universe (the atoms we are made of), while the nature of the dominant mass component (the dark matter) remains elusive. However, because of its abundance, dark matter is a significant driver of both the dynamics of stars and galaxies and of their formation and evolution.
