DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PhysBound/2/
 ">A Carrollian Perspective on Celestial Holography</a>\nby Laura Donnay as
  part of Physics @ Boundaries Workshop\n\n\nAbstract\nA Carrollian Perspec
 tive on Celestial Holography\nAbstract: In this talk\, we will present a h
 olographic description of gravity in 4d asymptotically flat spacetime in t
 erms of a 3d sourced conformal Carrollian field theory. The external sourc
 es encode the leaks of gravitational radiation at null infinity. The Ward 
 identities of this theory are shown to reproduce those of the 2d celestial
  CFT after relating Carrollian to celestial operators. This suggests a new
  set of interplays between gravity in asymptotically flat spacetime\, sour
 ced conformal Carrollian field theory and celestial CFT.\n
