TL;DR

This paper explores a noncommutative geometry-inspired black hole model with a smeared mass distribution, revealing unique horizon structures and temperature behavior, suggesting potential dark matter candidates.

Contribution

Introduces a black hole model with noncommutative geometry effects, showing modified horizon structure and temperature behavior, advancing understanding of microscopic black hole properties.

Findings

Black holes can have zero, one, or two horizons depending on mass.

Hawking temperature vanishes as mass approaches zero.

Potential dark matter candidates due to dense, frozen matter.

Abstract

We study a black hole with a blurred mass density instead of a singular one, which is caused by the noncommutativity of 3-space. Depending on its mass, such object has either none, one or two event horizons. It possesses properties, which become important on a microscopic scale, in particular, the Hawking temperature does not increase indefinitely as the mass goes to zero, but vanishes instead. Such frozen and extremely dense pieces of matter are good dark matter candidates.
