Séminaire – Laura Bernard (LUX/Obs. Paris)
" Building analytical waveforms to challenge General Relativity" In this talk, I will give an overview of why the post-Newtonian formalism is still relevant to model gravitational waves, focusing on recent synergies with other techniques and research topics. Taking the example of effective...
