- W3201700910 abstract "The most accurate model to describe the gravitational interaction is the well-known theory of General Relativity. Several observational evidences corroborate the legitimacy of the theory compared to the older Newtonian gravity. General Relativity furthermore predicts the existence of gravitational waves, i.e. spacetime ripples produced by accelerated masses. Thanks to a connected network of interferometers called LIGO/Virgo, gravitational waves from the coalescence of massive and compact astrophysical bodies have been measured directly. These recent observations paved the way to a completely new route to test the gravitational interaction. The possibility of using gravitational waves to obtain a deeper understanding of open problems within General Relativity motivates the work developed in this thesis. Each part is essentially devoted to challenging the current model of gravitation, sometimes including yet undiscovered new matter fields, and other times modifying the theoretical framework of General Relativity. In the first part of this manuscript, I discuss the astrophysical consequences of the presence of scalar fields permeating galaxies. A detailed picture of the interaction of massive black holes and scalar dark matter structures is provided. The second part is dedicated to the analysis of the generation and propagation of gravitational waves. As an example, I examine the close limit approximation as a promising tool to investigate the collision of extreme compact objects. The last part of this thesis instead focuses on unstable mechanisms around black holes and stars (scalarization and vectorization), in two alternative models of gravitation." @default.
