Numerical evolution of realistic binary black holes: application of the dynamical horizon formalism to the accurate estimation of physical parameter in gravitational waves

Objective

Gravitational waves physics constitutes one of the most vigorous lines of research in gravity physics, as well as a radically new avenue in astronomy. Extraction of astrophysical information from the gravitational wave data collected by interferometric gravitational antennae, demands the accurate modeling of the sources.

Binary black hole coalescence represents a singularly important astrophysical source for gravitational radiation, whose dynamics must be studied by using numerical relativity techniques. The precise characterization of the individual black hole physical parameters, during the evolution of the system, is critical for the correct interpretation of the observational data. This defines the main goal of this project: the accurate determination of black hole parameters and corresponding emitted waveforms, in the numerical evolution of astrophysically realistic binary black holes configurations.

This ultimate goal is structured in three partial objectives:
- translation of the local description of black holes (dynamical horizons) into the schemes employed in numerical relativity;
- numerical construction of binary black hole spacetimes by using the spectral methods implemented in the C++ Lorene library (Meudon group); and
- extraction of the astrophysical relevant content.

This program naturally continues the applicant's work during his previous Marie Curie Fellowship, devoted to the construction of binary black hole initial data. The final outcome of the present project would consist in a set of accurate gravitational waveforms to be used in the analysis of observational data.

The IAA-CSIC gravitation group provides an excellent setting for the re-incorporation of the applicant: it would enable him to join an interdisciplinary program in black hole horizons research, in the context of which he would be in charge of the numerical/astrophysical aspects. This would complete the scheduled transfer of knowledge to a less-favoured European region (Andalucia).
