# Dual gravitational charges and soft theorems

## TL;DR

This paper explores how dual gravitational charges influence the phase space of radiating modes, leading to a new soft NUT theorem and relaxing boundary conditions at spacelike infinity.

## Contribution

It introduces the concept of dual gravitational charges and demonstrates their implications for soft theorems and boundary conditions in gravitational theories.

## Key findings

- Existence of dual gravitational charges implies a new soft NUT theorem.
- Dual charges remove the need for boundary conditions at spacelike infinity.
- The phase space of radiating modes is affected by these dual charges.

## Abstract

We consider the consequences of the dual gravitational charges for the phase space of radiating modes, and find that they imply a new soft NUT theorem. In particular, we argue that the existence of these new charges removes the need for imposing boundary conditions at spacelike infinity that would otherwise preclude the existence of NUT charges.
