Abstract
Formulating a precise notion of holography between gravity in asymptotically flat spacetime and a lower-dimensional field theory remains an outstanding problem. In this paper, the authors discuss two seemingly disparate existing approaches to such a duality, namely the celestial and Carrolian holography, and show that they are connected by an integral transform.
