Perturbatively Exact $w_{1 + \infty}$ 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…

$(2, 2)$ Scattering and the Celestial Torus

Alexander Atanasov, Adam Ball, Walker Melton +2

Analytic continuation from Minkowski space to $(2, 2)$ split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under th…
