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…
GW150914 peak frequency: a novel consistency test of strong-field General Relativity
Gregorio Carullo, Gunnar Riemenschneider, Ka Wa Tsang +2
We introduce a novel test of General Relativity in the strong-field regime of a binary black hole coalescence. Combining information coming from Numerical Relativity simulations of…
A standard siren measurement of the Hubble constant from GW170817 without the electromagnetic counterpart
M. Fishbach, R. Gray, I. Magaña Hernandez +316
We perform a statistical standard siren analysis of GW170817. Our analysis does not utilize knowledge of NGC 4993 as the unique host galaxy of the optical counterpart to GW170817.…
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…
Rush the inspiral: efficient Effective One Body time-domain gravitational waveforms
Alessandro Nagar, Piero Rettegno
Computationally efficient waveforms are of central importance for gravitational wave data analysis of inspiralling and coalescing compact binaries. We show that the post-adiabatic…
Matter imprints in waveform models for neutron star binaries: tidal and self-spin effects
Tim Dietrich, Sebastian Khan, Reetika Dudi +16
The combined observation of gravitational and electromagnetic waves from the coalescence of two neutron stars marks the beginning of multi-messenger astronomy with gravitational wa…
Factorization and resummation: A new paradigm to improve gravitational wave amplitudes. II: the higher multipolar modes
Francesco Messina, Alberto Maldarella, Alessandro Nagar
The factorization and resummation approach of Nagar and Shah~[Phys.~Rev.~D~94 (2016), 104017], designed to improve the strong-field behavior of the post-Newtonian (PN) residual wav…
