# Tower of subleading dual BMS charges

## TL;DR

This paper extends the dual gravitational charges to include the entire BMS symmetry algebra and introduces subleading dual charges that complement existing BMS charges, covering all Newman-Penrose charges.

## Contribution

It introduces subleading dual BMS charges and extends dual charges away from null infinity, completing the set of Newman-Penrose charges.

## Key findings

- Dual charges for the full BMS algebra are established.
- Subleading dual charges are defined away from null infinity.
- All Newman-Penrose charges are accounted for by these dual and subleading charges.

## Abstract

We supplement the recently found dual gravitational charges with dual charges for the whole BMS symmetry algebra. Furthermore, we extend the dual charges away from null infinity, defining subleading dual charges. These subleading dual charges complement the subleading BMS charges in the literature and together account for all the Newman-Penrose charges.
