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…
S-algebra in Gauge Theory: Twistor, Spacetime and Holographic Perspectives
Adam Kmec, Lionel Mason, Romain Ruzziconi +1
The celestial -algebra arose from a reinterpretation of collinear limits of the Yang-Mills S-matrix as OPEs in celestial holography. It was subsequently represented via asymptot…
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…
On AdS deformations of celestial symmetries
Roland Bittleston, Giuseppe Bogna, Simon Heuveline +3
Celestial holography has led to the discovery of new symmetry algebras arising from the study of collinear limits of perturbative gravity amplitudes in flat space. We explain from…
