-Forms on the Celestial Sphere
Laura Donnay, Erfan Esmaeili, Carlo Heissenberg
We construct a basis of conformal primary wavefunctions (CPWs) for -form fields in any dimension, calculating their scalar products and exhibiting the change of basis between co…
Bridging Carrollian and Celestial Holography
Laura Donnay, Adrien Fiorucci, Yannick Herfray +1
Gravity in asymptotically flat spacetime constitutes the archetypal example of a gravitational system with leaky boundary conditions. Pursuing our analysis of [1], we argue th…
Loop-corrected subleading soft theorem and the celestial stress-tensor
Laura Donnay, Kevin Nguyen, Romain Ruzziconi
We demonstrate that the one-loop exact subleading soft graviton theorem automatically follows from conservation of the BMS charges, provided that the hard and soft fluxes separatel…
Goldilocks Modes and the Three Scattering Bases
Laura Donnay, Sabrina Pasterski, Andrea Puhm
We consider massless scattering from the point of view of the position, momentum, and celestial bases. In these three languages different properties of physical processes become ma…
Carrollian Perspective on Celestial Holography
Laura Donnay, Adrien Fiorucci, Yannick Herfray +1
We show that a sourced conformal Carrollian field theory has the right kinematic properties to holographically describe gravity in asymptotically flat spacetime. The exte…
