Numerical-Relativity-Informed Effective-One-Body model for Black-Hole-Neutron-Star Mergers with Higher Modes and Spin Precession
Alejandra Gonzalez, Rossella Gamba, Matteo Breschi +4
We present the first effective-one-body (EOB) model for generic-spins quasi-circular black-hole--neutron-star (BHNS) inspiral-merger-ringdown gravitational waveforms (GWs). Our mod…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
Comparing second-order gravitational self-force and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries II: the large-mass-ratio case
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We compare recently computed waveforms from second-order gravitational self-force (GSF) theory to those generated by a new, GSF-informed, effective one body (EOB) waveform model fo…
Comparing second-order gravitational self-force, numerical relativity and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We present the first systematic comparison between gravitational waveforms emitted by inspiralling, quasi-circular and nonspinning black hole binaries computed with three different…
Towards a gravitational self force-informed effective-one-body waveform model for nonprecessing, eccentric, large-mass-ratio inspirals
Alessandro Nagar, Simone Albanesi
Building upon several recent advances in the development of effective-one-body models for spin-aligned eccentric binaries with individual masses we introduce a new EOB…
Inferring eccentricity evolution from observations of coalescing binary black holes
Alice Bonino, Rossella Gamba, Patricia Schmidt +5
The origin and formation of stellar-mass binary black holes remains an open question that can be addressed by precise measurements of the binary and orbital parameters from their g…
Virgo Detector Characterization and Data Quality during the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave signals in the past few years, alongside the two LIGO ins…
Strong-field scattering of two spinning black holes: Numerics versus Analytics
Seth Hopper, Alessandro Nagar, Piero Rettegno
We present new Numerical Relativity calculations of the scattering angle between two, equal-mass, black holes on hyperbolic-like orbits. We build upon previous work considering…
New Avenue for Accurate Analytical Waveforms and Fluxes for Eccentric Compact Binaries
Simone Albanesi, Andrea Placidi, Alessandro Nagar +2
We introduce a new paradigm for constructing accurate analytic waveforms (and fluxes) for eccentric compact binaries. Our recipe builds on the standard Post-Newtonian (PN) approach…
The Virgo O3 run and the impact of the environment
F. Acernese, M. Agathos, A. Ain +486
Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient…
Numerical-relativity validation of effective-one-body waveforms in the intermediate-mass-ratio regime
Alessandro Nagar, James Healy, Carlos O. Lousto +2
One of the open problems in developing binary black hole (BBH) waveforms for gravitational wave astronomy is to model the intermediate mass ratio regime and connect it to the extre…
Assessment of Effective-One-Body Radiation Reactions for Generic Planar Orbits
Simone Albanesi, Alessandro Nagar, Sebastiano Bernuzzi +2
In this paper we assess the performances of different analytical prescriptions for the effective-one-body (EOB) radiation reaction along generic planar orbits using exact numerical…
