Kinematic reconstruction of torsion as dark energy in Friedmann cosmology

TL;DR

This paper investigates whether space-time torsion can explain dark energy by reconstructing its evolution using observational cosmological data and kinematic models.

Contribution

It introduces a method to reconstruct the torsion function directly from observational data within a kinematic framework, exploring torsion as a dark energy candidate.

Findings

Torsion function reconstructed from data shows consistency with dark energy behavior.

Kinematic models effectively constrain torsion parameters using supernovae, Hubble, and BAO data.

Results support torsion as a viable alternative explanation for cosmic acceleration.

Abstract

In this paper we study the effects of torsion of space-time in the expansion of the Universe as a candidate to dark energy. The analysis is done by reconstructing the torsion function along cosmic evolution by using observational data of Supernovae type Ia, Hubble parameter {and Baryon Acoustic Oscillation} measurements. We have used a kinematic model for the parameterization of the comoving distance and the Hubble parameter, then the free parameters of the models are constrained by observational data. The reconstruction of the torsion function is obtained directly from the data, using the kinematic parameterizations.
