2d theory for asymptotic dynamics of 4d (self-dual) Einstein gravity
Wei Bu, Sean Seet
In this paper, we present a simple chiral 2d theory living on a momentum space celestial sphere whose behaviour exactly produces various IR dynamics of recent resurged interests fo…

A systematic approach to celestial holography: a case study in Einstein gravity
Wei Bu, Sean Seet
We propose a systematic approach to celestial holography in massless theories beginning by studying the implications of properly incorporating field configurations built using the…
