Abstract

The dynamics of black hole spacetimes play a crucial role in astrophysics, high energy physics and fundamental physics. In this thesis I have investigated the dynamics of black holes in generic spacetimes by extending established numerical relativity methods to higher dimensional or non-asymptotically flat spacetimes. Additionally, I have explored BH spacetimes perturbed my massive scalar fields. By developing and further improving NR techniques I have been able to push our knowledge to new grounds.
