# Extremal noncommutative black holes as dark matter furnaces

## TL;DR

This paper explores the potential role of extremal noncommutative black holes as dark matter relics that could act as cosmic furnaces, fueled by dark matter accretion, and examines their thermodynamic properties at the evaporation endpoint.

## Contribution

It introduces the concept of extremal noncommutative black holes as stable dark matter relics and hypothesizes their thermal equilibrium state fueled by dark matter accretion.

## Key findings

- Dark matter annihilation occurs near noncommutative black holes.
- Hypothesized existence of a thermal equilibrium state of black hole relics.
- Black hole relics could serve as dark matter furnaces.

## Abstract

In this letter, we consider dark matter annihilation in the gravitational field of noncommutative black holes. At final stage of evaporation, we hypothesize the existence of a thermal equilibrium state composed of a burning black hole relics fueled by dark matter accretion.
