Celestial Symmetries of Black Hole Horizons
Romain Ruzziconi, Céline Zwikel
We establish a correspondence between the gravitational phase space at null infinity and the subleading phase space near a finite-distance null hypersurface, such as a black hole h…
Celestial Symmetries and Subleading Phase Space of Null Hypersurfaces
Romain Ruzziconi, Céline Zwikel
Pursuing our analysis of [1], we study the gravitational solution space around a null hypersurface in the bulk of spacetime, such as a black hole or a cosmological horizon. We disc…
The symplectic potential for leaky boundaries
Robert McNees, Céline Zwikel
Charges associated with gauge symmetries are defined on boundaries of spacetimes. But these constructions typically involve divergent quantities when considering asymptotic boundar…
(Anti)-de Sitter with leaky boundaries and corners
Robert McNees, Céline Zwikel
We construct charges for four-dimensional spacetimes with a non-vanishing cosmological constant, including charges that are not conserved because of a leaky boundary and charges as…
