Abstract:

In recent years, quantum field theory (QFT)-inspired descriptions of the two-body problem in gravity have advanced the state of the art in gravitational-wave physics computation. In this talk, I will revisit some of the fundamentals of the on-shell scattering amplitude programme for binary black holes, with a particular focus on spinning effects. I will describe black hole scattering amplitudes using the Post-Minkowskian expansion within a heavy-particle effective field theory. Finally, I will demonstrate how to incorporate non-conservative effects, such as absorption, using a QFT description.

Speaker Bio:

Dr. Rafael Aoude obtained his PhD at the University of Mainz, working on EFTs for colliders and scattering amplitudes. He then moved to Belgium for a postdoctoral position at UCLouvain, followed by another postdoc at the University of Edinburgh. Currently, he is a Junior Staff at DESY, working on EFTs, collider phenomenology, and gravitational waves.
