Expanding on the double copy in null Fermi coordinates
Samarth Chawla, Kwinten Fransen, Cynthia Keeler
We propose a Weyl classical double copy for a Fermi normal coordinate expansion around null geodesics. To leading order in this "Penrose expansion", we recover a previously propose…
The Penrose limit of the Weyl double copy
Samarth Chawla, Kwinten Fransen, Cynthia Keeler
We embed the Penrose limit into the Weyl classical double copy. Thereby, we provide a lift of the double copy properties of plane wave spacetimes into black hole geometries and we…
Black Hole Horizons from the Double Copy
Samarth Chawla, Cynthia Keeler
We describe a procedure for locating black hole horizons in Kerr-Schild spacetimes in the double copy paradigm. Using only single- and zeroth-copy data on flat spacetime, our proce…
Aligned Fields Double Copy to Kerr-NUT-(A)dS
Samarth Chawla, Cynthia Keeler
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 family. Using a multi-Kerr-Schil…
