Can the Chaplygin gas be a plausible model for dark energy?

Abstract

In this paper two cosmological models representing the flat Friedmann universe filled with a Chaplygin fluid, with or without dust, are analyzed in terms of the recently proposed ``statefinder'' parameters. Trajectories of both models in the parameter plane are shown to be significantly different with respect to the ``quiessence'' and ``tracker'' models. The generalized Chaplygin gas model with an equation of state of the form $p=\ensuremath{-}A/{\ensuremath{\rho}}^{\ensuremath{\alpha}}$ is also analyzed in terms of the statefinder parameters.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
