Weyl double copy in bimetric massive gravity
Hugo GarcÃa-Compeán, César I. Ramos
The Weyl double copy formalism, which relates the Weyl spinor with the square of the field strength, is studied in the context of Hassan-Rosen bigravity for stationary and time-dep…

PlebaÅski-DemiaÅski solutions in bigravity and Kerr-Schild double copy relations using an effective metric
Hugo GarcÃa-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…
