Phantom Appearance of Non-phantom Matter in Anisotropic Cosmological Model

Abstract

Two cosmological models with non-phantom matter having the same expansion of the universe as phantom cosmologies are constructed in anisotropic Bianchi type-V universe. The exact solutions to the corresponding Einstein field equations have been obtained. The statefinder diagnostic pair i. e. {r,s} parameters have been obtained for disordered radiation i. e. γ=1/3. We have also discussed the well-known astrophysical phenomena, namely the look-back time, luminosity distance and event horizon with redshift. © 2012 Springer Science+Business Media, LLC.
