Note on the asymptotic structure of Kerr-Schild form by Pujian Mao, Weicheng Zhao

“…Abstract The Kerr-Schild form provides a natural way of realizing the classical double copy that relates exact solutions in general relativity to exact solutions in gauge theory. …”

Kerr-Schild double field theory and classical double copy by Kanghoon Lee

“…Abstract The Kerr-Schild (KS) formalism is a powerful tool for constructing exact solutions in general relativity. In this paper, we present a generalization of the conventional KS formalism to double field theory (DFT) and supergravities. …”

An axially symmetric spacetime with causality violation in Ricci-inverse gravity by J. C. R. de Souza, A. F. Santos

“…Other spacetimes, such as Gödel and Gödel-type universes, which are exact solutions of general relativity and allow for causality violations, are also explored in Ricci-inverse gravity framework.…”

The Tolman VII space-time in the presence of charge and a cosmological constant by James Ripple, Anish Agashe

“…Abstract The Tolman VII space-time is one of the few physically acceptable exact solutions in general relativity. In this paper, we derive a generalised Tolman VII solution which includes a charge and a cosmological constant. …”

Self-similar collapse in Painlevé–Gullstrand coordinates by Soumya Chakrabarti, Chiranjeeb Singha

“…Abstract We report a family of self-similar exact solutions in General Relativity. The solutions are found in a Painleve-Gullstrand coordinate system but can also be transformed smoothly into a diagonal form. …”

The Kerr-Schild double copy in Lifshitz spacetime by Gökhan Alkaç, Mehmet Kemal Gümüş, Mustafa Tek

“…Abstract The Kerr-Schild double copy is a map between exact solutions of general relativity and Maxwell’s theory, where the nonlinear nature of general relativity is circumvented by considering solutions in the Kerr-Schild form. …”
