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…
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…
Comparing effective-one-body and Mathisson-Papapetrou-Dixon results for a spinning test particle on circular equatorial orbits around a Kerr black hole
Angelica Albertini, Viktor Skoupý, Georgios Lukes-Gerakopoulos +1
We consider a spinning test particle around a rotating black hole and compare the Mathisson-Papapetrou-Dixon (MPD) formalism under the Tulczyjew-Dixon spin supplementary condition…
Effective-one-body waveform model for non-circularized, planar, coalescing black hole binaries: the importance of radiation reaction
Alessandro Nagar, Rossella Gamba, Piero Rettegno +2
We present an updated version of the TEOBResumS-Dali effective-one-body (EOB) waveform model for spin aligned binaries on non-circularized orbits. Recently computed 4PN (nonspinnin…
