Cosmological tests of sudden future singularities

We discuss combined constraints, coming from the cosmic microwave background shift parameter R, the baryon acoustic oscillations distance parameter A, and from the latest type la supernovae data, imposed on cosmological models which allow sudden future singularities of pressure. We show that due to...

Description
Summary:	We discuss combined constraints, coming from the cosmic microwave background shift parameter R, the baryon acoustic oscillations distance parameter A, and from the latest type la supernovae data, imposed on cosmological models which allow sudden future singularities of pressure. We show that due to their weakness such sudden singularities may happen in the very near future and that at present they can mimic standard dark energy models.
