A multipolar effective one body waveform model for spin-aligned black hole binaries
Alessandro Nagar, Gunnar Riemenschneider, Geraint Pratten +2
We introduce \TEOBiResumSM{}, an improved version of the effective-one-body (EOB) waveform model \TEOBResumS{} for spin-aligned, coalescing black hole binaries, that includes subdo…
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…
Quasi-5.5PN TaylorF2 approximant for compact binaries: point-mass phasing and impact on the tidal polarizability inference
Francesco Messina, Reetika Dudi, Alessandro Nagar +1
We derive a point-mass (nonspinning) frequency-domain TaylorF2 phasing approximant at quasi-5.5 post-Newtonian (PN) accuracy for the gravitational wave from coalescing compact bina…
Nonlinear-in-spin effects in effective-one-body waveform models of spin-aligned, inspiralling, neutron star binaries
Alessandro Nagar, Francesco Messina, Piero Rettegno +5
Spinning neutron stars acquire a quadrupole moment due to their own rotation. This quadratic-in-spin, self-spin effect depends on the equation of state (EOS) and affects the orbita…
Effective-one-body multipolar waveform for tidally interacting binary neutron stars up to merger
Sarp Akcay, Sebastiano Bernuzzi, Francesco Messina +3
Gravitational-wave astronomy with coalescing binary neutron star sources requires the availability of gravitational waveforms with tidal effects accurate up to merger. This article…
Time-domain effective-one-body gravitational waveforms for coalescing compact binaries with nonprecessing spins, tides and self-spin effects
Alessandro Nagar, Sebastiano Bernuzzi, Walter Del Pozzo +21
We present TEOBResumS, a new effective-one-body (EOB) waveform model for nonprecessing (spin-aligned) and tidally interacting compact binaries.Spin-orbit and spin-spin effects are…
