Magnetized anisotropic dark energy cosmological models in scale covariant theory of gravitation

Abstract

In the present paper, we have investigated Bianchi type II, VIII and IX spacetime in the presence of magnetized anisotropic dark energy in the Scale covariant theory of gravitation. Exact solution of the field equations are obtained by assuming the expansion anisotropy (the ratio of shear scalar to expansion scalar) to be a function of average scale factor. The isotropy of the fluid, space and expansion are examined.

“…The result is similar to the result obtained by Beghel and Singh (2012) and Singh and Debnath (2009). The result is consistent with cosmological observational data (Katore et al 2014a).…”

“…(17) and (18) respectively. We get same result as Beesham (1986), Beghel and Singh (2012), Katore et al (2014a). The result is also consistent with recent observational data (Katore et al 2014a).…”

“…They diverge for large time. It deserves to mention that the result is consistent with the cosmological observations (Katore et al 2014a). …”

“…This is in complete agreement with the Big Bang scenario. Similar results are also obtained by Singh and Beesham (2011) and Katore et al (2014a).…”

“…At t = 0, they were constant, afterward they start to evolve with time and finally diverge at large time. It is analogous to Singh and Beesham (2011) and Katore et al (2014a). …”
