Applied these Lagrangians to model Kerr black hole interactions

Provided a new perspective on black hole dynamics using higher spin fields

Abstract

We give a brief introduction into the gauge invariant formulation of irreducible massive bosonic higher spin fields. We discuss both free Lagrangians and the ones which include cubic interactions. We demonstrate an application of these Lagrangians to a description of the interactions between Kerr black holes in a Post Minkowskian approximation.
