On AdS 4 deformations of celestial symmetries
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 the twistor perspective how a non-vanishing cosmological constant Λ naturally modifies the celestial chiral algebra. The...
