R. Colistete Jr., J. C. Fabris, S. V. B. Goncalves, P. E. de Souza
TL;DR
This paper explores the use of the Chaplygin gas as a unified model for dark energy and dark matter, supported by observational constraints.
Contribution
It proposes and evaluates the Chaplygin gas as a novel unified model for dark energy and dark matter based on observational data.
Findings
Chaplygin gas can describe dark energy and dark matter as a unified component
Observational constraints favor the Chaplygin gas model
Supports the viability of unified dark sector models
Abstract
The possibility that the dark energy may be described by the Chaplygin gas is discussed. Some observational constraints are established. These observational constraints indicate that a unified model for dark energy and dark matter through the employement of the Chaplygin gas is favored.
