High-order effective-one-body tidal interactions and gravitational scattering
Malte Schulze, Sebastiano Bernuzzi, Piero Rettegno +3
Using state-of-the-art scattering results in post-Minkowskian (PM) gravity, we improve the tidal sector of four different flavors of the effective-one-body (EOB) formalism. We nota…
A novel Lagrange-multiplier approach to the effective-one-body dynamics of binary systems in post-Minkowskian gravity
Thibault Damour, Alessandro Nagar, Andrea Placidi +1
We present a new approach to the conservative dynamics of binary systems, within the effective one-body (EOB) framework, based on the use of a Lagrange multiplier to impose the mas…
Gravitational scattering of two neutron stars
Joan Fontbuté, Sebastiano Bernuzzi, Piero Rettegno +2
We present the first numerical relativity simulations of the gravitational scattering of two neutron stars. Constraint-satisfying initial data for two equal-mass nonspinning sequen…
Radiation reaction force for scalar-tensor theories in effective-one-body formalism
Tamanna Jain, Piero Rettegno
Whilst most of the binary configurations in modified theories of gravity are studied under quasi-circular orbit limit, eccentricity effects could play a significant role in future…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Effective-one-body waveform model for noncircularized, planar, coalescing black hole binaries II:high accuracy by improving logarithmic terms in resummations
Alessandro Nagar, Danilo Chiaramello, Rossella Gamba +5
Effective-one-body (EOB) models are based on analytical building blocks that, mathematically, are truncated Taylor series with logarithms. These functions are usually resummed usin…
