| Abstract: Our current understanding of galaxy formation is based on the presence of an elusive
matter component: the Cold Dark Matter CDM. This simple model has ben challenged many times in the past decade, mainly by galaxy observations on small scales: from the abundance of satellites, to the distribution of dark matter within galaxies, and more recently by the discovery of galaxies "without" dark matter.
In my talk I will first review all these claims with the help of cosmological numerical simulations of galaxy formation from the NIHAO project. I will then discuss whether there is indeed an observationally motivated need to abandon Cold Dark Matter and move beyond such a simple model. Link to the Event Video |
