Logarithmic supertranslations as asymptotic symmetries of gravity at null infinity
Oscar Fuentealba, Marc Henneaux, Sébastien Robert +1
Logarithmic supertranslations have been shown recently to be symmetries of the gravitational field at spatial infinity. We extend this work by proving explicitly that they are also…
A Covariant Formulation of Logarithmic Supertranslations at Spatial Infinity
Florian Girelli, Simon Langenscheidt, Giulio Neri +2
We investigate the asymptotic symmetries of asymptotically flat spacetimes at spatial infinity. We propose a new symplectic structure and conservative boundary conditions in a poly…
Teleparallel gravity at null infinity
Florian Girelli, Jianhui Qiu, Céline Zwikel
Four-dimensional asymptotically flat spacetimes have been central to recent developments in infrared physics. Gravitational waves reaching the asymptotic boundary reveal an infinit…
Symmetries of the gravitational scattering in the absence of peeling
Marc Geiller, Alok Laddha, Céline Zwikel
The symmetries of the gravitational scattering are intimately tied to the symmetries which preserve asymptotic flatness at null infinity. In Penrose's definition of asymptotic flat…
The partial Bondi gauge: Gauge fixings and asymptotic charges
Marc Geiller, Céline Zwikel
In the companion paper [SciPost Phys. 13, 108 (2022), arXiv:2205.11401 [hep-th]] we have studied the solution space at null infinity for gravity in the partial Bondi gauge. This pa…
The partial Bondi gauge: Further enlarging the asymptotic structure of gravity
Marc Geiller, Céline Zwikel
We present a detailed analysis of gravity in a partial Bondi gauge, where only the three conditions are fixed. We relax in particular the so-called determinant co…
3d gravity in Bondi-Weyl gauge: charges, corners, and integrability
Marc Geiller, Christophe Goeller, Céline Zwikel
We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to…
