Observational constraints on the unified dark matter and dark energy model based on the quark bag model
(Elsevier, 2014-06-02)
In this work we investigate if a small fraction of quarks and gluons, which escaped hadronization and survived as a uniformly spread perfect fluid, can play the role of both dark matter and dark energy. This fluid, as ...
Anisotropic expansion and SNIa: An open issue
(Elsevier, 2015-02-04)
We review the appropriateness of using SNIa observations to detect potential signatures of anisotropic expansion in the Universe. We focus on Union2 and SNLS3 SNIa datasets and use the hemispherical comparison method to ...
