A unified Scenario for modeling the Galactic and Cosmological Dark Matter Components

TL;DR

This paper explores the potential of a single scalar field model to simultaneously explain galactic and cosmological dark matter, aiming for a unified approach within gravitational frameworks.

Contribution

It introduces a scalar field model that could unify the description of dark matter at galactic and cosmological scales, expanding previous separate models.

Findings

Scalar field models can fit galactic dark matter profiles.

Unified models may explain both galactic and cosmological dark matter.

The approach is compatible with asymptotically flat or deSitter spacetimes.

Abstract

In this work we analyze the viability of use a particular models of scalar fields in the context of the galactic dark matter problem. These models are based on a single scalar field, minimally coupled to the gravity in a asymptotically flat or asymptotically deSitter spacetime. We discuss the opening possibility of constructing a unified model for both the cosmological and the galactic dark matter.
