The simplicity of black holes and beyond
A priori a theoretical prediction of the best tested theory of gravity that we have to this day - General Relativity - there is now complementary observational evidence that black holes do, indeed, exist in the universe. Moreover, all observational data seems to confirm the theoretical prediction that black holes can be described by a very small number of conserved quantities, namely mass, charge and angular momentum, and hence black holes seem to be fascinatingly simple - in contrast to other compact objects without event horizon such as neutron stars. However, models appearing in theories that try to explain e.g. the nature of dark energy or the inflationary epoch in the primordial universe as well as recent studies in applications of the gauge/gravity duality contain black hole solutions that often carry so-called "hair", i.e. non-trivial fields on the event horizon. In this talk, I will give a review on the current understanding of black hole properties and present examples and applications of black holes that possess "hair".
