Celestial holography: An asymptotic symmetry perspective

L Donnay - Physics Reports, 2024‏ - Elsevier
We review the role that infinite-dimensional symmetries arising at the boundary of
asymptotically flat spacetimes play in the context of the celestial holography program. Once …

Carrollian perspective on celestial holography

L Donnay, A Fiorucci, Y Herfray, R Ruzziconi - Physical Review Letters, 2022‏ - APS
We show that a 3D sourced conformal Carrollian field theory has the right kinematic
properties to holographically describe gravity in 4D asymptotically flat spacetime. The …

Lectures on celestial holography

AM Raclariu - arxiv preprint arxiv:2107.02075, 2021‏ - arxiv.org
These notes consist of 3 lectures on celestial holography given at the Pre-Strings school
2021. We start by reviewing how semiclassically, the subleading soft graviton theorem …

Holographic symmetry algebras for gauge theory and gravity
