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…
Orbital eccentricity in general relativity from catastrophe theory
Matteo Boschini, Nicholas Loutrel, Davide Gerosa +1
While the orbital eccentricity is a key feature of the gravitational two-body problem, providing an unambiguous definition in general relativity poses significant challenges. Despi…
Inferring Interference: Identifying a Perturbing Tertiary with Eccentric Gravitational Wave Burst Timing
Isobel M. Romero-Shaw, Nicholas Loutrel, Michael Zevin
[Abridged] Binary black holes may form and merge dynamically. These binaries are likely to become bound with high eccentricities, resulting in a burst of gravitational radiation at…
