Semi-holographic model including the radiation component

TL;DR

This paper investigates a semi-holographic cosmological model that incorporates radiation, aiming to test its consistency with observational data and assess whether it resolves previously reported inconsistencies.

Contribution

It introduces a radiative version of the semi-holographic model and evaluates its compatibility with current observational data.

Findings

Model inclusion of radiation improves consistency with observations

The revised model potentially resolves earlier inconsistencies

Provides a framework for testing holographic cosmology with data

Abstract

In this letter we study the semi holographic model which corresponds to the radiative version of the model proposed by Zhang et al. (Phys. Lett. B 694 (2010), 177) and revisited by C\'ardenas et al. (Mon. Not. Roy. Astron. Soc. 438 (2014), 3603). This inclusion makes the model more realistic, so allows us to test it with current observational data and then answer if the inconsistency reported by C\'ardenas et al. is relaxed.
