Metric reconstruction from celestial multipoles
Geoffrey Compère, Roberto Oliveri, Ali Seraj
The most general vacuum solution to Einstein's field equations with no incoming radiation can be constructed perturbatively from two infinite sets of canonical multipole moments, w…
Extended corner symmetry, charge bracket and Einstein's equations
Laurent Freidel, Roberto Oliveri, Daniele Pranzetti +1
We develop the covariant phase space formalism allowing for non-vanishing flux, anomalies and field dependence in the vector field generators. We construct a charge bracket that ge…
The Weyl BMS group and Einstein's equations
Laurent Freidel, Roberto Oliveri, Daniele Pranzetti +1
We propose an extension of the BMS group, which we refer to as Weyl BMS or BMSW for short, that includes, besides super-translations, local Weyl rescalings and arbitrary diffeomorp…
A note on dual gravitational charges
Roberto Oliveri, Simone Speziale
Dual gravitational charges have been recently computed from the Holst term in tetrad variables using covariant phase space methods. We highlight that they originate from an exact 3…
Gravitational multipole moments from Noether charges
G. Compère, R. Oliveri, A. Seraj
We define the mass and current multipole moments for an arbitrary theory of gravity in terms of canonical Noether charges associated with specific residual transformations in canon…
Near-horizon Extreme Kerr Magnetospheres
G. Compère, R. Oliveri
Analytical solutions to force-free electrodynamics around black holes are fundamental for building simple models of accretion disk and jet dynamics. We present a (nonexhaustive) cl…
