Carrollian and celestial spaces at infinity
José Figueroa-O'Farrill, Emil Have, Stefan Prohazka +1
We show that the geometry of the asymptotic infinities of Minkowski spacetime (in dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups of spatial…

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_{…

Celestial IR divergences and the effective action of supertranslation modes
Kevin Nguyen, Jakob Salzer
Infrared divergences in perturbative gravitational scattering amplitudes have been recently argued to be governed by the two-point function of the supertranslation Goldstone mode o…
