Self-Dual Black Holes in Celestial Holography
Erin Crawley, Alfredo Guevara, Elizabeth Himwich +1
We construct two-dimensional quantum states associated to four-dimensional linearized rotating self-dual black holes in signature Klein space. The states are comprised of g…

Towards Gravity From a Color Symmetry
Alfredo Guevara
Using tools from color-kinematics duality we propose a holographic construction of gravitational amplitudes, based on a 2d Kac-Moody theory on the celestial sphere. In the $N\to \i…

Reconstructing Classical Spacetimes from the S-Matrix in Twistor Space
Alfredo Guevara
We present a holographic construction of solutions to the gravitational wave equation starting from QFT scattering amplitudes. The construction amounts to a change of basis from mo…
