A shorter path to celestial currents

A bstract Here we consider what happens when lift a codimension-1 slice of the celestial sphere to bulk spacetime in manner that respects our ability quotient by null generators I ± get codimension-2 hologram. The contour integrals 2D currents for symmetries boundary standard 2-form gauge theory on this novel choice surface and Ward identities follow directly from Noether’s theorem.
