Coincident morphological transitions in precessing black-hole binaries

Davide Gerosa, Giulia Foroni, Giulia Fumagalli +1

We present new insights into the phenomenology of post-Newtonian spin precession in black-hole binaries. Using multi-timescale methods, previous work has shown that the precession…

Systematic biases due to waveform mismodeling in parametrized post-Einsteinian tests of general relativity: The impact of neglecting spin precession and higher modes

Rohit S. Chandramouli, Kaitlyn Prokup, Emanuele Berti +1

We study the robustness of parametrized post-Einsteinian (ppE) tests of General Relativity (GR) with gravitational waves, due to waveform inaccuracy. In particular, we determine th…
