AdS Celestial Symmetries: from Ambitwistor charges to CFT Light-Ray Operators
Alex Goodenbour, Adam Kmec, Lionel Mason +1
The algebra is the cosmological-constant deformation of the celestial symmetry algebra of gravity, providing an infinite-dimensional extension o…
Quasi-Local Celestial Charges and Multipoles
Adam Kmec, Lionel Mason, Romain Ruzziconi
We extend Penrose's quasi-local mass definition to include higher-spin charges associated with the celestial symmetries and relate them to traditional definitions o…
Celestial charges from a twistor action
Adam Kmec, Lionel Mason, Romain Ruzziconi +1
The celestial symmetries in asymptotically flat spacetimes have a natural geometric interpretation on twistor space in terms of Poisson diffeomorphisms. Using this…
Carrollian Amplitudes and Celestial Symmetries
Lionel Mason, Romain Ruzziconi, Akshay Yelleshpur Srikant
Carrollian holography aims to express gravity in four-dimensional asymptotically flat spacetime in terms of a dual three-dimensional Carrollian CFT living at null infinity. Carroll…
Nonlinear Gravitons, Null Geodesics, and Holomorphic Disks
Claude LeBrun, L. J. Mason
We develop a global twistor correspondence for pseudo-Riemannian conformal structures of signature (++--) with self-dual Weyl curvature. Near the conformal class of the standard in…
