  • A multi-timescale analysis of phase transitions in precessing black-hole binaries 

    Gerosa, Davide; Kesden, Michael; Sperhake, Ulrich; Berti, Emanuele; O'Shaughnessy, Richard (APSPhysical Review D, 2015-09-14)
    The dynamics of precessing binary black holes (BBHs) in the post-Newtonian regime has a strong timescale hierarchy: the orbital timescale is very short compared to the spin-precession timescale which, in turn, is much ...

  • Distinguishing black-hole spin-orbit resonances by their gravitational wave signatures. II: Full parameter estimation 

    Trifirò, Daniele; O'Shaughnessy, Richard; Gerosa, Davide; Berti, Emanuele; Kesden, Michael; Littenberg, Tyson; Sperhake, Ulrich (American Physical Society, 2016)
    Gravitational waves from coalescing binary black holes encode the evolution of their spins prior to merger. In the post-Newtonian regime and on the precession timescale, this evolution has one of three morphologies, with ...

  • Multi-timescale analysis of phase transitions in precessing black-hole binaries 

    Gerosa, Davide; Kesden, Michael; Sperhake, Ulrich; Berti, Emanuele; O'Shaughnessy, Richard (American Physical SocietyPhysical Review D, 2015)
    The dynamics of precessing binary black holes (BBHs) in the post-Newtonian regime has a strong timescale hierarchy: the orbital timescale is very short compared to the spin-precession timescale which, in turn, is much ...

  • Precessional instability in binary black holes with aligned spins 

    Gerosa, Davide; Kesden, Michael; O'Shaughnessy, Richard; Klein, Antoine; Berti, Emanuele; Sperhake, Ulrich; Trifirò, Daniele (American Physical SocietyPhysical Review Letters, 2015-10-02)
    Binary black holes on quasicircular orbits with spins aligned with their orbital angular momentum have been testbeds for analytic and numerical relativity for decades, not least because symmetry ensures that such configurations ...
