Probing modified gravitational-wave dispersion with bursts from eccentric black-hole binaries
Nicholas Loutrel, Ava Bailey, Davide Gerosa
Gravitational waves in general relativity are non-dispersive, yet a host of modified theories predict dispersion effects during propagation. In this work, we consider the impact of…
PRECESSION 2.1: black-hole binary spin precession on eccentric orbits
Giulia Fumagalli, Davide Gerosa, Nicholas Loutrel
We present version 2.1 of the public code {\sc precession}, a Python module for studying the post-Newtonian dynamics of precessing black hole binaries. In this release, we extend t…
Non-adiabatic dynamics of eccentric black-hole binaries in post-Newtonian theory
Giulia Fumagalli, Nicholas Loutrel, Davide Gerosa +1
Eccentric black-hole binaries are among the most awaited sources of gravitational waves, yet their dynamics lack a consistent framework that provides a detailed and physically robu…

Nicholas Loutrel, Nicolas Yunes
Spin precession in compact binaries is intricately tuned to the multipole structure of the underlying bodies. For black holes, violations of the no-hair theorems induced by modific…
Inspiralling compact objects with generic deformations
Nicholas Loutrel, Richard Brito, Andrea Maselli +1
Self-gravitating bodies can have an arbitrarily complex shape, which implies a much richer multipolar structure than that of a black hole in General Relativity. With this motivatio…
