# Non-Spherically Symmetric Collapse in Asymptotically AdS Spacetimes

## TL;DR

This paper numerically investigates non-spherical gravitational collapse in five-dimensional asymptotically AdS spacetimes, revealing faster collapse times and lower mass thresholds compared to spherical cases.

## Contribution

It introduces the first numerical simulations of non-spherical collapse in AdS, demonstrating how asymmetry affects collapse dynamics and black hole formation.

## Key findings

- Non-spherical configurations collapse faster than spherical ones.
- Less mass is needed for collapse within a fixed time in non-spherical cases.
- Formation of multiple black holes on the axis observed.

## Abstract

We numerically simulate gravitational collapse in asymptotically anti-de Sitter spacetimes away from spherical symmetry. Starting from initial data sourced by a massless real scalar field, we solve the Einstein equations with a negative cosmological constant in five spacetime dimensions and obtain a family of non-spherically symmetric solutions, including those that form two distinct black holes on the axis. We find that these configurations collapse faster than spherically symmetric ones of the same mass and radial compactness. Similarly, they require less mass to collapse within a fixed time.
