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.
