Celestial algebra in Einstein-Yang-Mills theory
Shreyansh Agrawal, Panagiotis Charalambous, Laura Donnay
From a study of the subleading structure of the asymptotic equations of motion in Einstein-Yang-Mills theory, we construct charges that are conserved up to quadratic order in non-r…
Logarithmic doublets in CCFT
Agnese Bissi, Laura Donnay, Beniamino Valsesia
We investigate the presence of logarithmic CFT doublets in the soft sector of celestial CFT related with supertranslations. We show that the quantum operator associated with a $\lo…
Carrollian representation from twistor space
Laura Donnay, Laurent Freidel, Yannick Herfray
We construct an explicit realization of the action of the loop algebra on fields at null infinity. This action is directly derived by Penrose transform of the geome…
