Plebański-Demiański solutions in bigravity and Kerr-Schild double copy relations using an effective metric
Hugo García-Compeán, César I. Ramos
In this work a formalism for proportional generalized double Kerr-Schild ansatz in bigravity is considered, where both metrics are coupled to matter. We study time-dependent and st…

Hyper-Hermitian Weyl Double Copy
E. Chacón, H. García-Compeán, G. Robles
The self-dual double copy is further explored. In previous work, it has been shown that hyper-Hermitian manifolds also have associated the self-dual gauge theories via Kerr-Schild…

Classical Kerr-Schild double copy in bigravity for maximally symmetric spacetimes
H. García-Compeán, C. Ramos
A generalized Kerr-Schild ansatz for bigravity, already considered in the literature, which leads to linear interactions between the metrics is used to study the bigravity equation…
