This article constructs BMS momentum fluxes starting from gravity in asymptotically flat spacetime, establishes the relation between the BMS momentum fluxes and celestial CFT operators, and deduces the transformation under the action of asymptotic symmetries and the OPEs of the celestial CFT currents from the BMS flux algebra.
Starting from gravity in asymptotically flat spacetime, the BMS momentum fluxes are constructed. These are non-local expressions of the solution space living on the celestial Riemann surface. They transform in the coadjoint representation of the extended BMS group and correspond to Virasoro primaries under the action of bulk superrotations. The relation between the BMS momentum fluxes and celestial CFT operators is then established: the supermomentum flux is related to the supertranslation operator and the super angular momentum flux is linked to the stress-energy tensor of the celestial CFT. The transformation under the action of asymptotic symmetries and the OPEs of the celestial CFT currents are deduced from the BMS flux algebra.
