  We propose a regularization procedure in the sourced Weyl double copy, a
spinorial version of the classical double copy, such that it matches much more
general results in the Kerr-Schild version. In the regularized Weyl double
copy, the anti-de Sitter (AdS) and the Lifshitz black holes, which form the
basis of the study of strongly coupled gauge theories at finite temperature
through the AdS/CFT correspondence and its non-relativistic generalization,
become treatable. We believe that this might pave the way for finding out a
relation between the classical double copy and holography.
