Compactifying the Kerr-Schild double copy
We show that the classical double copy relationship for Kerr-Schild spacetimes can be dimensionally reduced to give a natural notion of the double...

Kerr-Schild double copy for Kundt spacetimes of any dimension
We show that vacuum type N Kundt spacetimes in an arbitrary dimension admit a Kerr-Schild (KS) double copy. This is mostly done in a...

Classical Kerr-Schild double copy in bigravity for maximally symmetric spacetimes
A generalized Kerr-Schild ansatz for bigravity, already considered in the literature, which leads to linear interactions between the metrics is used...

Celestial holography on Kerr-Schild backgrounds
We explore the celestial holography proposal for non-trivial asymptotically flat backgrounds including the Coulomb field of a static and spinning...

Note on the asymptotic structure of Kerr-Schild form
The Kerr-Schild form provides a natural way of realizing the classical double copy that relates exact solutions in general relativity to exact...

Double-extended Kerr–Schild form for 5D electrovacuum solutions
Five-dimensional Einstein–Maxwell–Chern–Simons equations are investigated in the framework of an extended Kerr–Schild strategy to search for black...

Double Kerr-Schild spacetimes and the Newman-Penrose map
The Newman-Penrose map, which is closely related to the classical double copy, associates certain exact solutions of Einstein’s equations with...

Kerr–Schild metrics in teleparallel gravity
We show that the Kerr–Schild ansatz can be extended from the metric to the tetrad, and then to teleparallel gravity where curvature vanishes but...

Heterotic Kerr-Schild Double Field Theory and its double Yang-Mills formulation
We present a formulation of heterotic Double Field Theory (DFT), where the fundamental fields are in O ( D, D ) representations. The theory is obtained...

The Kerr-Schild double copy in Lifshitz spacetime
The Kerr-Schild double copy is a map between exact solutions of general relativity and Maxwell’s theory, where the nonlinear nature of general...

Kerr–Schild–Kundt metrics in generic gravity theories with modified Horndeski couplings
The Kerr–Schild–Kundt (KSK) metrics are known to be one of the universal metrics in general relativity, which means that they solve the vacuum field...

The classical double copy for M-theory from a Kerr-Schild ansatz for exceptional field theory
We construct the classical double copy formalism for M-theory. This extends the current state of the art by including the three form potential of...
-
Kerr-Schild double copy and complex worldlines
We use the classical double copy to identify a necessary condition for Maxwell theory sources to constitute single copies of Kerr-Schild solutions to...

Isometries and the double copy
In the standard derivation of the Kerr-Schild double copy, the geodicity of the Kerr-Schild vector and the stationarity of the spacetime are...

Conserved charges of the Kerr black hole revisited
We revisit the Kerr black hole as cast in the Boyer–Lindquist, Kerr–Schild and Weyl canonical coordinates, and calculate its total mass/energy and...

Aligned fields double copy to Kerr-NUT-(A)dS
We find Abelian gauge fields that double copy to a large class of black hole spacetimes with spherical horizon topology known as the Kerr-NUT-(A)dS...

A Rutherford-like formula for scattering off Kerr-Newman BHs and subleading corrections
By exploiting the Kerr-Schild gauge, we study the scattering of a massive (charged) scalar off a Kerr-Newman black hole. In this gauge, the...

The ultrarelativistic limit of Kerr
The massless (or ultrarelativistic) limit of a Schwarzschild black hole with fixed energy was determined long ago in the form of the Aichelburg-Sexl...

Appell’s Correspondence Unifies Gravity with Quantum Theory
AbstractFollowing Carter, Israel, López et al., we consider the over-rotating Kerr–Newman (KN) black hole solutions as classical gravitating electron...
