Gauss-Bonnet dynamical compactification scenarios and their ghosts in the tensor sectors
Antonio De Felice, François Larrouturou
In a cosmological context, the Einstein-Gauss-Bonnet theory contains, in dimensions, a dynamical compactification scenario in which the additional dimensions settle down to a…
Gravitational ringdown in the Minimal Theory of Massive Gravity
Hugo Roussille, François Larrouturou
This work focuses on gravitational perturbations of black holes in the self-accelerating branch of the Minimal Theory of Massive Gravity (MTMG). This theory is a healthy extension…
Testing regularity of black holes with X-rays and Gravitational Waves
Swarnim Shashank
Physically relevant solutions in general relativity often contain spacetime singularities, which are typically interpreted as a sign of breakdown of the theory at high densities/cu…
Multipole expansion at the level of the action in -dimensions
Loris Amalberti, François Larrouturou, Zixin Yang
In this paper we study the multipole expansion of the long-wavelength effective action for radiative sources in (+1) spacetime dimensions. We present detailed expressions for th…
Electromagnetic fields in compact binaries: post-Newtonian wave generation and application to double white dwarfs systems
Quentin Henry, François Larrouturou, Christophe Le Poncin-Lafitte
The aim of this work is twofold: (i) to properly define a wave-generation formalism for compact-supported sources embedded in Einstein-Maxwell theory, relying on matched post-Newto…
Uncovering stochastic gravitational-wave backgrounds with LISA
Quentin Baghi, Nikolaos Karnesis, Jean-Baptiste Bayle +2
Finding a stochastic gravitational-wave background (SGWB) of astrophysical or primordial origin is one of the quests of current and future gravitational-wave observatories. While d…

Quentin Henry, François Larrouturou
This work deals with the tail and ``failed'' tail sectors of the conservative dynamics for compact binary systems at the 5PN order. We employ the Fokker Lagrangian method with dime…
Gravitational-wave tails of memory at 4PN order
David Trestini, Luc Blanchet
We study a novel cubic nonlinear effect, the tails-of-memory, which consist of a combination of the tail effect (backscattering of linear gravitational waves against the curvature…

Elisa Maggio
Gravitational waves provide a unique opportunity to test gravity in the dynamical and nonlinear regime. We present a parametrized test of general relativity (GR) that introduces ge…
Gravitational waves from compact binaries to the fourth post-Newtonian order
