Advanced Virgo Plus for O5 -- Design Report Overview
F. Acernese, A. Agapito, D. Agarwal +578
This document presents an overview of the design, implementation, and expected performance of the Advanced Virgo Plus (AdV+) upgrades in view of the O5 observing run. Following the…
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…
Charged Black-Hole Binary Evolution at Second Post-Newtonian Order
Andrea Placidi, Elisa Grilli, Marta Orselli +3
We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive th…
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…
Exploring the gauge flexibility of the linear-in-spin effective-one-body Hamiltonian at the 5.5 post-Newtonian order
Andrea Placidi, Luca Sebastiani, Gianluca Grignani
We derive the gauge-general expressions of the two gyro-gravitomagnetic functions entering the spin-orbit sector of the effective-one-body (EOB) Hamiltonian up to the fifth-and-hal…
Direct current memory effects in effective-one-body waveform models
Elisa Grilli, Andrea Placidi, Simone Albanesi +2
The direct current (DC) memory is a non-oscillatory, hereditary component of the gravitational wave (GW) signal that represents one of the most peculiar manifestations of the nonli…
