Contribution

It introduces a novel inflationary model based on modified Chaplygin gas and reconstructs the inflaton potential using observational constraints.

Findings

Model fits early and late acceleration phases.

Identifies shortcomings between inflation and dark energy epochs.

Compatible with recent observational data.

Abstract

In this paper, we considered an inflationary model that effectively behaves as a modified Chaplygin gas in the context of quintessence cosmology. We reconstructed the inflaton potential bottom-up and using the recent observational data we fixed the free parameters of the model. We showed that the modified Chaplygin gas inspired model is suitable for both the early and the late time acceleration but has shortcomings between the two periods.
