Black hole formation from massive scalar fields

TL;DR

This paper demonstrates that under certain conditions, the gravitational collapse of a massive scalar field can be approximated as dust collapse, providing a criterion for black hole formation based on initial parameters.

Contribution

It introduces a new criterion for black hole formation from massive scalar fields by showing collapse can resemble dust under specific parameters.

Findings

Collapse can be approximated as dust in certain parameter ranges

Black hole formation depends on initial size, mass, and scalar field mass

Provides a criterion for black hole formation based on initial conditions

Abstract

It is shown that there exists a range of parameters in which gravitational collapse with a spherically symmetric massive scalar field can be treated as if it were collapsing dust. This implies a criterion for the formation of black holes depending on the size and mass of the initial field configuration and the mass of the scalar field.
