Intermediate evolution using SNIa, and BAO

TL;DR

This paper compares intermediate evolution cosmological models with power-law models and finds that intermediate evolution better fits low-redshift observations from supernovae and BAO, matching the standard Lambda-CDM model.

Contribution

It demonstrates that the intermediate evolution model provides a superior fit to low-redshift data compared to power-law models, aligning closely with Lambda-CDM.

Findings

Intermediate evolution fits low-redshift data better than power-law models.

The model is as consistent with observations as Lambda-CDM.

Supports the viability of intermediate evolution as a cosmological model.

Abstract

We study the intermediate evolution model and show that, compared with the recent study of a power-law evolution, the intermediate evolution is a better description of the low-redshift regime supported by observations from type Ia supernovae and BAO. We found also that recent data suggest that the intermediate evolution is as good a fit to this redshift range as the $\Lambda$CDM model.
