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, multi-timescale analysis of the binary dynamics able to capture both precession and eccentricity over long inspirals. We show that the evolution of an eccentric binary can be reduced that of effective source on quasi-circular orbits, coupled to a post-Newtonian prescription for the secular evolution of the eccentricity. Our findings unveil an interplay between precession and eccentricity: the spins of eccentric binaries precess on shorter timescales and their nutation amplitude is altered compared to black holes on quasi-circular orbits, consequently affecting the so-called spin morphology. Even if binaries circularize by the time they enter the sensitivity window of our detectors, their spin orientations retain some memory of the past evolution on eccentric orbits, thus providing a new link between gravitational-wave detection and astrophysical formation. At the same time, we point out that residual eccentricity should be considered a source of systematics when reconstructing the past history of black-hole binaries using the spin orientations.

  1. Trails of clouds in binary black holes

    gr-qc 2025-12 conditional novelty 7.0 of 10

    Boson clouds around binary black holes generically deplete through orbital resonances, driving eccentricity and spin-orbit tilt toward fixed points—including off-equatorial ones—leaving observable gravitational-wave trails.

  2. Impact of numerical-relativity waveform calibration on parametrized post-Einsteinian tests

    gr-qc 2026-03 accept novelty 6.0 of 10

    NR late-inspiral calibration systematics in IMRPhenomD produce false ppE GR violations at O5 SNRs ≳60; an uncertainty-aware baseline restores consistency with GR up to SNR 330.

  3. Coincident morphological transitions in precessing black-hole binaries

    gr-qc 2025-08 conditional novelty 6.0 of 10

    Every coincident double or triple spin-morphology transition in post-Newtonian black-hole binaries is derived analytically, giving closed-form radii (rwide, rUD±) and parameter conditions for five allowed cases and on...

    gr-qc 2025-02 conditional novelty 6.0 of 10

    The paper presents pyEFPE, a validated and publicly available frequency-domain post-Newtonian waveform model for inspiralling precessing-eccentric compact binaries, with up to about a fifteen-fold speedup.

    A review of population synthesis: the codes, the environments, and the predicted rates and features of gravitational wave sources, with an emphasis on breaking degeneracies.
