The accuracy of merger times in hierarchical black hole triples
Giulia Fumagalli, Alejandro Vigna-Gómez
Orbit-averaged equations are widely used to model the gravitational-wave-driven evolution of compact binaries. Their validity relies on the radiation-reaction timescale being much…
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…
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…
Distinguishing the Origin of Eccentric Black Hole Mergers with Gravitational-wave Spin Measurements
Jakob Stegmann, Davide Gerosa, Isobel Romero-Shaw +3
It remains an open question whether the binary black hole mergers observed with gravitational-wave detectors originate from the evolution of isolated massive binary stars or were d…
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…
Residual eccentricity as a systematic uncertainty on the formation channels of binary black holes
Giulia Fumagalli, Isobel Romero-Shaw, Davide Gerosa +3
Resolving the formation channel(s) of merging binary black holes is a key goal in gravitational-wave astronomy. The orbital eccentricity is believed to be a precious tracer of the…
The impact of outliers on pulsar timing arrays
Giulia Fumagalli, Golam Shaifullah, Alberto Sesana
The detection of gravitational waves with Pulsar Timing Arrays (PTAs) requires precise measurement of the difference between the pulsars' timing models and their observed pulses, a…
Spin-eccentricity interplay in merging binary black holes
Giulia Fumagalli, Davide Gerosa
Orbital eccentricity and spin precession are precious observables to infer the formation history of binary black holes with gravitational-wave data. We present a post-Newtonian, mu…
Efficient multi-timescale dynamics of precessing black-hole binaries
Davide Gerosa, Giulia Fumagalli, Matthew Mould +4
We present analytical and numerical progress on black-hole binary spin precession at second post-Newtonian order using multi-timescale methods. In addition to the commonly used eff…
