# NUT-like and near-horizon limits of Kerr-NUT-(A)dS spacetimes

## TL;DR

This paper explores specific limits of higher-dimensional Kerr-NUT-(A)dS spacetimes, revealing new geometries with enhanced symmetries, including Taub-NUT-(A)dS and near-horizon geometries, characterized by additional Killing vectors.

## Contribution

It introduces a novel limiting procedure for Kerr-NUT-(A)dS spacetimes that produces geometries with increased symmetries and decomposed Killing tensors.

## Key findings

- Derived Taub-NUT-(A)dS geometries as limits.
- Obtained extreme near-horizon geometries.
- Showed symmetry enhancement via additional Killing vectors.

## Abstract

We study a class of limits of the higher-dimensional Kerr-NUT-(A)dS spacetimes where particular roots of metric functions degenerate. Namely, we obtain the Taub-NUT-(A)dS and the extreme near-horizon geometries as two examples of our limiting procedure. The symmetries of the resulting spacetimes are enhanced which is manifested by the presence of supplementary Killing vectors and decomposition of Killing tensors into Killing vectors.
