A proof of conservation laws in gravitational scattering: tails and breaking of peeling
Geoffrey Compère, Geoffrey Compère, Sébastien Robert +1
We propose a definition of asymptotically flat spacetimes that is consistent with both null infinities and compatible with known properties of gravitational scattering, incoming an…
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…
Electromagnetic multipole expansions and the logarithmic soft photon theorem
Geoffrey Compère, Dima Fontaine, Kevin Nguyen
We study the general structure of the electromagnetic field in the vicinity of spatial infinity. Starting from the general solution of the sourced Maxwell equations written in term…
Approach to the separatrix with eccentric orbits
Guillaume Lhost, Geoffrey Compère
Eccentric binary compact mergers are prime targets of current and future gravitational wave observatories. In the small mass ratio expansion, post-adiabatic inspirals have been mod…
Tidal Love numbers and quasi-normal modes of the Schwarzschild-Hernquist black hole
Sumanta Chakraborty, Geoffrey Compère, Ludovico Machet
We derive the model of the Schwarzschild black hole immersed into a dark matter halo with a relativistic Hernquist profile, the Schwarzschild-Hernquist black hole, and obtain its t…
Self-force framework for transition-to-plunge waveforms
Lorenzo Küchler, Geoffrey Compère, Leanne Durkan +1
Compact binaries with asymmetric mass ratios are key expected sources for next-generation gravitational wave detectors. Gravitational self-force theory has been successful in produ…
