Anisotropic expansion and SNIa: An open issue
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 ...
Cosmological constrains on fast transition Unified Dark Matter models
(IOP Publishing, 2015)
In this work we show the results obtained applying a Unified Dark Matter (UDM) model with a fast transition to a set of cosmological data. Two different functions to model the transition are tested, and the feasibility of ...
