Abstract: The talk will be split in two parts. In part I we present a new infinite dimensional symmetry algebra underlying scattering of gluons and gravitons. It extends the leading and subleading generators by an infinite tower of soft modes located at negative integer weights. We derive the corresponding OPEs and show how this is the minimal consistent extension of previous results. Based on hep-th/2103.03961.

In part II we will analyze celestial holography in the context of 3D models such as large-N O(N) and Chern-Simons matter theory. In these models a non-perturbative computation can be carried out leading to novel features in the celestial 4-point function, including crossing-symmetry relations and the conformal partial wave expansion, extending previous work of Lam and Shao. Work in progress with J. Kulp, J. Wu (Perimeter) and Garcia-Sepulveda (Chicago).
