In recent years, the modelling of gravitational wave sources has become a cornerstone of theoretical and numerical relativity. Multiple communities – working with distinct formalisms such as Self-Force, Effective One Body (EOB), Effective Field Theory (EFT) and post-Newtonian approximations – have developed powerful tools to describe the two-body problem with increasing precision. Each of these approaches is advanced enough to come with its own set of language, notation, conceptual framework, and computational tools.
The workshop aims to bridge this gap and bring these communities closer together. This will be done by providing a mix of beginner friendly lectures, hands on coding sessions, plenary overviews together with state of the art research talks for each of the fields.
In particular, there will be three type of sessions:
* Plenary Talks: Delivered by senior experts, providing an overview of the approach, its history, strengths, and current challenges, especially those that might benefit from dialogue with other methods;
* Pedagogical Lectures: first a theoretical introduction to the key concepts, notation, and logic of the framework, followed by a practical session, which is aimed at demonstrating how to compute a simple observable using available software or symbolic tools;
* Early Career Scientist Presentations: 30 minutes talks by junior researchers (PhD students and junior postdocs) showing how they have used the techniques described in the lectures to obtain novel results.
Throughout the lectures, a central objective will be to illustrate, within each formalism, the computation of the radiated flux, guiding participants step by step through the derivation and evaluation of this key observable.
The Workshop will also allot a considerable amount of time to Q and A sessions. This time will have a crucial importance, given the pedagogical nature of the Workshop.
