Dynamics of domain walls intersecting black holes

TL;DR

This paper investigates how a small black hole interacts with and potentially escapes from a domain wall, using simulations to track the process of separation and reconnection in a scalar field system.

Contribution

It provides a detailed simulation of black hole and domain wall interaction, including the black hole's escape mechanism, extending previous reconnection studies.

Findings

Confirmed previous results on black hole escape via reconnection.

Successfully simulated the entire evolution during black hole separation.

Illustrated the detailed process of black hole escape from a domain wall.

Abstract

Previous studies concerning the interaction of branes and black holes suggested that a small black hole intersecting a brane may escape via a mechanism of reconnection. Here we consider this problem by studying the interaction of a small black hole and a domain wall composed of a scalar field and simulate the evolution of this system when the black hole acquires an initial recoil velocity. We test and confirm previous results, however, unlike the cases previously studied, in the more general set-up considered here, we are able to follow the evolution of the system also during the separation, and completely illustrate how the escape of the black hole takes place.
