Abstract

A characteristic value formulation of the Weyl double copy leads to an
asymptotic formulation. We find that the Weyl double copy holds asymptotically
in cases where the full solution is algebraically general, using rotating STU
supergravity black holes as an example. The asymptotic formulation provides
clues regarding the relation between asymptotic symmetries that follows from
the double copy. Using the C-metric as an example, we show that a previous
interpretation of this gravity solution as a superrotation has a single copy
analogue relating the appropriate Li\'enard-Wiechert potential to a large gauge
transformation.
