The first direct detection of Gravitational Waves in 2015 by the LIGO experiment was a major breakthrough in our understanding of gravity. By measuring the Gravitational Wave signal emitted during the merger of two Black Holes and comparing it to theoretical predictions, it is now possible to test General Relativity in the strong gravity regime.
In this thesis, we focused on the ringdown part of the Gravitational Wave signal, characterised by complex frequencies called Quasi-Normal Modes, which govern the return to equilibrium of the disturbed Black Hole. We wish to study these frequencies in the case of Black Holes arising from Loop Quantum Gravity, an alternative theory of gravity, and analyse the deviations that appear with respect to General Relativity.
