Radiated Energy Spectrum, Radiated Angular Distribution and Non-linear Memory from the One-loop Gravitational Bremsstrahlung Waveform
Donato Bini, Thibault Damour, Stefano De Angelis +1
The frequency-domain gravitational waveform emitted by the scattering of two non-spinning massive particles has recently been derived at next-to-leading, \textit{i.e.} one-loop, po…
Quadrupolar bremsstrahlung waveform at the third-and-a-half post-Newtonian accuracy
Donato Bini, Thibault Damour, Andrea Geralico
We study the quadrupolar part of the gravitational waveform (encoded in the helicity-( radiative quadrupole moment $U_2 = \frac{1}{2!} \bar m^{i} \bar m^{j } U_{i j}…
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…
Remembering Yvonne Choquet-Bruhat
Thibault Damour
I describe the impact of some of the mathematical results of Yvonne Choquet-Bruhat on gravitational physics, as well as the evolution of my interactions with her over the years.
An Unfinished Collaboration with A. A. Starobinsky
Thibault Damour
The present text summarizes some of the results obtained in 2008 during the initial stages of a collaboration with Starobinsky which remained unfinished. The collaboration was an a…
High-post-Newtonian-order dynamical effects induced by tail-of-tail interactions in a two body system
Donato Bini, Thibault Damour, Andrea Geralico
Starting from the recently derived conservative tail-of-tail action [D. Bini and T. Damour, arXiv:2504.20204 [hep-th]] we compute several dynamical observables of binary systems (D…
