DESCRIPTION:Abstract: Holography in asymptotically flat spaces is one of t
 he most coveted goals of modern mathematical physics. In this talk\, I wil
 l motivate a novel holographic description of self-dual SO(8) Yang-Mills +
  self-dual conformal gravity on a Euclidean signature\, asymptotically fla
 t background called Burns space. The holographic dual lives on a D1-brane 
 wrapped along a CP^1 cycle in the twistor space of R^4 and is given by a g
 auged beta-gamma system with SO(8) flavor and a pair of defects at the nor
 th and south poles. It provides the first example of a stringy realization
  of (asymptotically) flat holography and is a Euclidean signature variant 
 of celestial holography. This is based on ongoing work with Kevin Costello
  and Natalie Paquette.
