Higher-spin algebras from soft theorems I: the wedge condition

Mathias Charbonnier, Javier Peraza

In this article we use the sub-soft graviton theorems to construct the map $\Top$ from the spin-graded set of holomorphic functions on local celestial sphere patches to differe…

Boundary Actions and Loop Groups: A Geometric Picture of Gauge Symmetries at Null Infinity

Silvia Nagy, Javier Peraza, Giorgio Pizzolo

In previous work arXiv:2407.13556, we proposed an extended phase space structure at null infinity accommodating large gauge symmetries for sub-leading soft theorems in Yang-Mil…

Periodic Analogs of Multiple Black Holes Solutions

Omar E. Ortiz, Javier Peraza

In this article, we extend the numerical studies developed in [arXiv:2210.12898] to construct periodic stationary axisymmetric solutions containing multiple horizons in each fundam…

Static vacuum 3+1 black holes that cannot be put into stationary rotation

Javier Peraza, Martin Reiris

We prove that some of the static Myers/Korotkin-Nicolai (MKN) vacuum 3+1 static black holes cannot be put into stationary rotation. Namely, they cannot be deformed into axisymmetri…

Periodic Kerr solution as an infinite soliton chain

Dmitry Korotkin, Javier Peraza

We combine numerical analysis with the inverse scattering method to study the periodic analog of Kerr solution. The periodic analog of the Schwarzschild solution is known to be reg…

A General Hierarchy of Charges at Null Infinity via the Todd Polynomials

Silvia Nagy, Javier Peraza, Giorgio Pizzolo

We give a general procedure for constructing an extended phase space for Yang-Mills theory at null infinity, capable of handling the asymptotic symmetries and construction of charg…
