Remarks On The Spherical Scalar Field Halo In Galaxies

TL;DR

This paper examines a scalar field model for galactic halos, emphasizing the importance of a specific condition in the metric to accurately interpret the physical nature and observable features of the halo.

Contribution

It identifies a crucial condition in the metric that must be maintained to correctly analyze the scalar field halo model in galaxies.

Findings

The full metric analysis reveals the true physical nature of the scalar field halo.

Maintaining the identified condition affects observable parameters significantly.

The study clarifies the interpretation of scalar field halos in galactic models.

Abstract

Matos, Guzman and Nunez proposed a model for the galactic halo within the framework of scalar field theory. We argue that an analysis involving the full metric can reveal the true physical nature of the halo only when a certain condition is maintained. We fix that condition and also calculate its impact on observable parameters of the model.
