Description
In an ongoing project, we are analyzing the response of a static black hole to (non-linear) perturbations by gravitational waves in the asymptotic regime. We now look to analyze what happens when the ingoing gravitational wave carries linear momentum and to compute the linear Bondi-Sachs momentum in the emitted radiation. In this talk, we will discuss some of the numerical set-up, and our approach towards computing the cross-section of the scattering process.
