Abstract:

 

The Detection of gravitational waves is eagely expected as one of the
most important scientific discoveries of the next decade. A worldwide
effort is now working actively to pursue this goal both at an
experimental level, by building ever sensitive detectors, and at a
theoretical level, by improving the modelling of the numerous sources of
gravitational waves. Much of this theoretical work is made through the
solution of the Einstein equations in those nonlinear regimes where no
analytic solutions are possible or known. I will review how this is done
in practice and highlight the considerable progress made recently in the
description of the dynamics of binary systems of black holes and neutron
stars. I will also discuss how the study of these systems provides
information well beyond that contained in the gravitational waveforms and
opens very exciting windows on the relativistic astrophysics of GRBs and
of the cosmological evolution of massive black holes.
