A parametrized model for gravitational waves from eccentric, precessing binary black holes: theory-agnostic tests of General Relativity with pTEOBResumS
Danilo Chiaramello, Nicolò Cibrario, Jacob Lange +4
Gravitational waves from binary black hole (BBH) mergers allow us to test general relativity in the strong-field, high-curvature regime. However, existing gravitational wave-based…
Binary black hole merger in the extreme mass ratio limit: a multipolar analysis of the inclined orbit case
Luca Nagni, Alessandro Nagar, Rossella Gamba +2
We compute the gravitational waveform emitted during the transition from quasi-spherical inspiral to plunge, merger and ringdown for a system of two black holes in the extreme mass…
Covariant and Gauge-invariant Metric-based Gravitational-waves Extraction in Numerical Relativity
Joan Fontbuté, Sebastiano Bernuzzi, Simone Albanesi +5
We revisit the problem of gravitational-wave extraction in numerical relativity with gauge-invariant metric perturbation theory of spherical spacetimes. Our extraction algorithm al…
Effective-one-body modeling for generic compact binaries with arbitrary orbits
Simone Albanesi, Rossella Gamba, Sebastiano Bernuzzi +3
We present the first unified model for the general relativistic dynamics and gravitational radiation of generic compact binaries. TEOBResumS-Dalà is a model based on the effective…
Scattering and dynamical capture of two black holes: synergies between numerical and analytical methods
Simone Albanesi, Alireza Rashti, Francesco Zappa +6
We study initially unbound systems of two black holes using numerical relativity (NR) simulations performed with GR-Athena++. We focus on regions of the parameter space close to th…
