Description
In the last few years a collection of novel approaches have lead to spectacular progress in the Post-Minkowskian description of the motion and gravitational wave emission of a two-body system. Analytical results in such approaches are obtained by studying a hyperbolic encounter using computational tools from high energy particle physics. These results can then be analytically continued to bound systems via the boundary-to-bound (B2B) dictionary, producing high-precision data needed for the construction of waveform templates. I will introduce the framework in which we perform these computations, talk a little bit about the computational tools, and review the ideas underlying the B2B map.
