The 22th July of 2020 Antoni Ramos Buades present his thesis: Gravitational waves from generic binary black holes: From numerical simulations to observational results.
This thesis gathers all the work done in my last four years of research focused on the production of numerical relativity simulations of generic binary black holes, as well as the analysis of the gravitational waveforms from these simulations and their implications for searches and parameter estimation on those systems.
I have started studying the prescription of initial parameters in numerical relativity simulations. A well known problem in numerical relativity is the difficulty to obtain simulations of black holes orbiting in quasicircular orbits due to inaccuracies of the initial data, which cause elliptical orbits with residual eccentricity. The first project of the thesis has been the development of a simple, iterative and computationally efficient procedure to reduce the eccentricity in binary black hole numerical relativity simulations, see Chap. 4. With this method we have produced quasicircular waveforms with negligible eccentricity, e ~ O(10-4), which have been used in our group to generate quasicircular waveform models.
