Abstract: In this talk, I will first discuss the challenges one faces when trying to explain the observed late-time acceleration of our Universe, due to the obstacles which the yet unkown physics of dark energy and dark matter place when we try to understand the true theory of gravity at large scales. In this context, I will further explain how model-independent observables have the potential to reveal whether gravity is truly modified at large scales, and will describe a fundamental, underlying relation between large-scale modifications of gravity and the (non-trivial) propagation of gravitational waves, as well as its observational implications for cosmology and astrophysics.

Explosion and final state of the charged black hole bomb

Abstract: I will present our results of a series of numerical relativity simulations of dynamical nonrotating black holes surrounded by self-gravitating scalar fields. In the non-charged case, even in the non-linear regime, quasistationary configurations of scalar fields are formed around black holes.
