Madrid's Polygonal Gravity Seminar Series

11:00h Welcome coffee
------------------------
11:30h First talk

Speaker: Pierre Vanhove (Institut de Physique Theorique, CEA, Saclay)

Title: From scattering amplitudes to gravitational waves observables

The necessity for high precision analytic computations of gravitational waves 
emitted from the gravitational two-body scattering in Einstein gravity has 
driven the development of scattering amplitudes techniques for classical 
gravitational observables. This approach has yielded analytic results that are 
in impressive agreement with those obtained from numerical general relativity.

In this presentation, we will elucidate the noteworthy correlation between the 
perturbative quantum scattering methodology and the classical post-Minkowskian 
expansion. This framework offers a coherent framework for comprehending 
gravitational radiation. Additionally, it provides a natural embedding of 
Einstein gravity into an effective field theory framework.

We will present a novel cubic formulation of gravity and demonstrate how this 
facilitates the computation of gravitational observables to all orders in 
perturbation.

15:00h Second talk

Speaker: Alessandro Nagar (INFN, Sezione di Torino)

Title: Effective-one-body modeling of coalescing binaries: status and 
perspectives

Abstract: I will present updated results in the construction of 
effective-one-body (EOB) based waveform model for coalescing compact binaries, 
leveraging on various perturbative calculations from post-Newtonian to 
post-Minkowskian methods.
