Skyrme fluid in anisotropic Universe

چکیده

Cosmological solutions are obtained in an anisotropic Kantowski-Sachs (KS) and Bianchi Type-I universes considering a cosmological constant with Skyrme fluid. Interestingly, the here both KS Bianchi-I found isotropize at late time due to presence of fluid even absence $\Lambda$ term or any inflationary mechanism involving inflaton field. A comparative study models carried out that universe admits oscillatory for given matter configuration. We also note emergent model can be The anisotropy, deceleration jerk parameters have been studied along linear perturbative stability explore efficacy model. Both stable besides their compatibility observational data. Thus, we claim possible source isotropization via accelerated expansion, which is capable reproducing some observed features universe.

Noether Symmetry in f(T) Theory at the anisotropic universe

As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...

How Anisotropic is Our Universe?

Large-scale cosmic microwave background anisotropies in homogeneous, globally anisotropic cosmologies are investigated. We perform a statistical analysis in which the four-year data from the Cosmic Background Explorer satellite is searched for the specific anisotropy patterns predicted by these models and thereby set definitive upper limits on the amount of shear, (σ/H)0 and vorticity, (ω/H)0, ...

Inflationary universe with anisotropic hair.

We study an inflationary scenario with a vector field coupled with an inflaton field and show that the inflationary Universe is endowed with anisotropy for a wide range of coupling functions. This anisotropic inflation is a tracking solution where the energy density of the vector field follows that of the inflaton field irrespective of initial conditions. We find a universal relation between th...

Anisotropic Bianchi Type-III Bulk Viscous Fluid Universe in Lyra Geometry

An anisotropic Bianchi type-III cosmological model is investigated in the presence of a bulk viscous fluid within the framework of Lyra geometry with time-dependent displacement vector. It is shown that the field equations are solvable for any arbitrary function of a scale factor. To get the deterministic model of the universe, we have assumed that (i) a simple power-law form of a scale factor ...

Discrete spectral shift in an anisotropic universe

In this paper we calculate the particle creation as seen by a stationary observer in an anisotropic universe. By using an observer and geometry dependent time to quantise a massive scalar field we show that a discrete energy spectrum shift occurs. The length scale associated with the geometry provides the energy scale by which the spectrum is shifted. The β(p, q) coefficient for the Bogolubov t...
