DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/11/">A 
 Carrollian Perspective on Celestial Holography</a>\nby Romain Ruzziconi (T
 U Wien) as part of AnLy Strings and Fields online seminars\n\n\nAbstract\n
 I will present a holographic description of gravity in 4d asymptotically f
 lat spacetime in terms of a 3d sourced conformal Carrollian field theory. 
 The external sources encode the leaks of gravitational radiation at null i
 nfinity. The Ward identities of this theory are shown to reproduce those o
 f the 2d celestial CFT after relating Carrollian to celestial operators. T
 his suggests a new set of interplays between gravity in asymptotically fla
 t spacetime\, sourced conformal Carrollian field theory and celestial CFT.
