Factorization and resummation: A new paradigm to improve gravitational wave amplitudes. III: the spinning test-body terms
Alessandro Nagar, Francesco Messina, Chris Kavanagh +4
We present new calculations of the energy flux of a spinning test-body on circular orbits around a Schwarzschild black hole at linear order in the particle spin. We compute the mul…
Spinning test-body orbiting around a Kerr black hole: circular dynamics and gravitational-wave fluxes
Georgios Lukes-Gerakopoulos, Enno Harms, Sebastiano Bernuzzi +1
In a recent work, [Phys. Rev. D. 94, 104010 (2016)], hereafter Paper I, we have numerically studied different prescriptions for the dynamics of a spinning particle in circular moti…
The most powerful astrophysical events: Gravitational-wave peak luminosity of binary black holes as predicted by numerical relativity
David Keitel, Xisco Jiménez Forteza, Sascha Husa +9
For a brief moment, a binary black hole (BBH) merger can be the most powerful astrophysical event in the visible universe. Here we present a model fit for this gravitational-wave p…
The evolution of hyperboloidal data with the dual foliation formalism: Mathematical analysis and wave equation tests
David Hilditch, Enno Harms, Marcus Bugner +2
A long-standing problem in numerical relativity is the satisfactory treatment of future null-infinity. We propose an approach for the evolution of hyperboloidal initial data in whi…
Spinning test-body orbiting around Schwarzschild black hole: circular dynamics and gravitational-wave fluxes
Enno Harms, Georgios Lukes-Gerakopoulos, Sebastiano Bernuzzi +1
We consider a spinning test-body in circular motion around a nonrotating black hole and analyze different prescriptions for the body's dynamics. We compare, for the first time, the…
Asymptotic gravitational wave fluxes from a spinning particle in circular equatorial orbits around a rotating black hole
Enno Harms, Georgios Lukes-Gerakopoulos, Sebastiano Bernuzzi +1
We present a new computation of the asymptotic gravitational wave energy fluxes emitted by a {\it spinning} particle in circular equatorial orbits about a Kerr black hole. The part…
The antikick strikes back: recoil velocities for nearly-extremal binary black hole mergers in the test-mass limit
Alessandro Nagar, Enno Harms, Sebastiano Bernuzzi +1
Gravitational waves emitted from a generic binary black-hole merger carry away linear momentum anisotropically, resulting in a gravitational recoil, or "kick", of the center of mas…
A new gravitational wave generation algorithm for particle perturbations of the Kerr spacetime
Enno Harms, Sebastiano Bernuzzi, Alessandro Nagar +1
We present a new approach to solve the 2+1 Teukolsky equation for gravitational perturbations of a Kerr black hole. Our approach relies on a new horizon penetrating, hyperboloidal…
Numerical solution of the 2+1 Teukolsky equation on a hyperboloidal and horizon penetrating foliation of Kerr and application to late-time decays
Enno Harms, Sebastiano Bernuzzi, Bernd Bruegmann
In this work we present a formulation of the Teukolsky equation for generic spin perturbations on the hyperboloidal and horizon penetrating foliation of Kerr recently proposed by R…
