Hidden Symmetry in the Double Copy
Adam Ball, Anna Bencke, Yaxi Chen +1
We show that the Killing tensor of the Kerr spacetime has an analogue in the gauge theory solution related to it by the classical double copy. This hidden symmetr…
Celestial Locality and the Jacobi Identity
Adam Ball
We show the equivalence of several different tests of the Jacobi identity for celestial currents at tree level, in particular finding a simple, practical condition on hard momentum…
Perturbatively Exact Asymptotic Symmetry of Quantum Self-Dual Gravity
Adam Ball, Sruthi Narayanan, Jakob Salzer +1
The infinite tower of positive-helicity soft gravitons in any minimally coupled, tree-level, asymptotically flat four-dimensional (4D) gravity was recently shown to generate a $w_{…
Global First Laws of Accelerating Black Holes
Adam Ball
We generalize the first law of black hole mechanics to the rotating, charged C-metric and to the Ernst metric, both of which have the charged C-metric as a special case. All of the…
Scattering and the Celestial Torus
Alexander Atanasov, Adam Ball, Walker Melton +2
Analytic continuation from Minkowski space to split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under th…
Accelerating Black Hole Thermodynamics with Boost Time
Adam Ball, Noah Miller
We derive a thermodynamic first law for the electrically charged C-metric with vanishing cosmological constant. This spacetime describes a pair of identical accelerating black hole…
