Higher-curvature corrections in black holes and the early universe through gravitational wave observations KU Leuven
General Relativity (GR) is broadly accepted as the correct description of the gravitational interaction when the curvature of spacetime is relatively low, but modifications of this theory are expected to arise at high energies. In an effective-field-theory approach, such modifications can be captured by introducing higher-curvature corrections in the Einstein's field equations. There has been a great interest in the literature in order to ...
