PRecise modelling of GRAvitational waves in Modified theories of gravity

In recent years, several theoretical and observational breakthroughs have led to the first detections of gravitational wave signals produced by mergers of black holes and neutron stars, ushering in the era of precision gravitational astronomy. The aim of the PRoGRAM project is to model the gravitational waves emitted by binary systems of compact objects in their spiral phase, in order to lay the groundwork to significantly improve tests of gravity performed with gravitational waves

To achieve this, various analytical methods such as the post-Newtonian and post-Minkowskian formalisms and effective field theory techniques will be used. The project is structured around three axes :

• The effective description of finite-size effects in alternative theories.
• Obtaining complete waveforms in some specific theories.
• The construction of a generic effective model applicable to a wide class of gravity theories.
