Perturbative black-hole and horizon solutions in gravity with explicit spacetime-symmetry breaking
Samy Aoulad Lafkih, Nils A. Nilsson, Marie-Christine Angonin +1
In this paper, we present static and spherically symmetric vacuum solutions to the mass-dimension action of an effective-field theory, choosing the diffeomorphism symmetr…
Hamiltonian normal forms for the post-Newtonian binary problem
Christopher Aykroyd, Adrien Bourgoin, Christophe Le Poncin-Lafitte
We revisit the dynamics of the post-Newtonian (PN) two-body problem for two inspiraling compact bodies. Starting from a matter-only reduced Hamiltonian, we present an adapted frame…
Reexamining aspects of spacetime-symmetry breaking with CMB polarization
Nils A. Nilsson, Christophe Le Poncin-Lafitte
The linear polarization of the Cosmic Microwave Background (CMB) is highly sensitive to parity-violating physics at the surface of last scattering, which might cause mixing of E an…
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…
Electromagnetic fields in compact binaries: a post-Newtonian approach
Quentin Henry, François Larrouturou, Christophe Le Poncin-Lafitte
Galactic binaries, and notably double white dwarfs systems, will be a prominent source for the future LISA and Einstein Telescope detectors. Contrarily to the black holes observed…
GENESIS: Co-location of Geodetic Techniques in Space
Pacôme Delva, Zuheir Altamimi, Alejandro Blazquez +39
Improving and homogenizing time and space reference systems on Earth and, more directly, realizing the Terrestrial Reference Frame (TRF) with an accuracy of 1mm and a long-term sta…
