Field-dependent diffeomorphisms and the transformation of surface charges between gauges
Luca Ciambelli, Marc Geiller
When studying gauge theories in the presence of boundaries, local symmetry transformations are typically classified as gauge or physical depending on whether the associated charges…
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…
Celestial charges and the subleading structure of asymptotically-flat spacetimes
Marc Geiller
We study the subleading structure of asymptotically-flat spacetimes and its relationship to the loop algebra of higher spin charges. We do so using both the Bondi-Sa…
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…
