Instead of null tests of GR, this approach takes forward modelling. A big step & congratulations to Banafsheh!!! Banafsheh has just started her second year of PhD (most of it has been during the pandemic), her family is in Iran&Turkey, we are so proud of her hard work and determination. Huge kudos to former group member Tanja Hinderer, who just left, it was such a fun collaboration (some photos attached of last night submission)! <LINK> @anwesh05 @GRAPPAinstitute Thank you! And of course Tanja, Néstor and Helvi! It was one of those papers where the team spirit was lovely and calm from start to end 🙌🏾 but the science very hard and required true strength and grit and perseverance from Banafsheh (speaking as a former post Newtonian dudette)",https://arxiv.org/abs/2012.09162,"Gravitational waves (GWs) from merging black holes allow for unprecedented probes of strong-field gravity. Testing gravity in this regime requires accurate predictions of gravitational waveform templates in viable extensions of General Relativity. We concentrate on scalar Gauss-Bonnet gravity, one of the most compelling classes of theories appearing as low-energy limit of quantum gravity paradigms, which introduces quadratic curvature corrections to gravity coupled to a scalar field and allows for black hole solutions with scalar-charge. Focusing on inspiralling black hole binaries, we compute the leading-order corrections due to curvature nonlinearities in the GW and scalar waveforms, showing that the new contributions, beyond merely the effect of scalar field, appear at first post-Newtonian order in GWs. We provide ready-to-implement GW polarizations and phasing. Computing the GW phasing in the Fourier domain, we perform a parameter-space study to quantify the detectability of deviations from General Relativity. Our results lay important foundations for future precision tests of gravity with both parametrized and theory-specific searches. ","Nonlinear curvature effects in gravitational waves from inspiralling
