Aspects of black hole scattering and the two-body problem in General Relativity
Summary
The merging of binary black hole systems is an event that can be observed by gravitational wave observatories. It is of high importance to understand these events and to be able to model them from a theoretical perspective. Observations of the inspiral phase of these mergers are nicely explained by known theoretical tools. In this thesis, we will study and develop tools to understand the post-merger phase. These tools emerge from studying quantum gravitational dynamics of black holes via scattering amplitudes.
