Enabling gravitational-wave astronomy with spin-precessing black holes on generic orbits
Aldo Gamboa, Lorenzo Pompili, Alessandra Buonanno +7
Binary black holes (BBHs) formed in dense stellar environments or in hierarchical triples can coalesce on eccentric orbits and carry spins of arbitrary orientation, leaving distinc…

Exploring the gauge flexibility of the linear-in-spin effective-one-body Hamiltonian at the 5.5 post-Newtonian order
Andrea Placidi, Luca Sebastiani, Gianluca Grignani
We derive the gauge-general expressions of the two gyro-gravitomagnetic functions entering the spin-orbit sector of the effective-one-body (EOB) Hamiltonian up to the fifth-and-hal…
