Coexistence of black holes and a long-range scalar field in cosmology

TL;DR

This paper introduces an exactly solvable scalar hairy black hole model that links black hole properties to a global scalar field, offering insights into dark energy and dark matter within cosmology.

Contribution

It presents a novel, exactly solvable black hole model with a scalar field that correlates black hole parameters with cosmological constants, unifying dark energy and dark matter descriptions.

Findings

Black holes are constrained by the scalar field parameters.

The model aligns with recent cosmological data.

It provides a unified framework for dark energy and dark matter.

Abstract

The exactly solvable scalar hairy black hole model (originated from the modern high-energy theory) is proposed. It turns out that the existence of black holes (BH) is strongly correlated to global scalar field, in a sense that they mutually impose bounds upon their physical parameters like the BH mass (lower bound) or the cosmological constant (upper bound). We consider the same model also as a cosmological one and show that it agrees with recent experimental data; additionally, it provides a unified quintessence-like description of dark energy and dark matter.
