Without exceeding the limits of the concordance cosmological model, all-scale scalar and vector perturbations of the homogeneous background are derived analytically for arbitrarily distributed inhomogeneities (discrete gravitating masses) as their nonrelativistic sources. The obtained expressions for the metric corrections converge everywhere in voids, have zero average values, and conform to...

The concordance cosmological model involving inflation describes the Universe very well. However, strict constraints are imposed by the recent observational data on the shape of the inflaton potential, excluding a lot of inflationary scenarios. We propose an alternative interpretation of the cosmic microwave background (CMB) data. We demonstrate that in the framework of the ΛCDM model...

In this talk, I'll start with the Cosmological Principle and its ramifications for the Cosmic Microwave Background Radiation. Mathematically speaking, statistical isotropy implies nonzero correlations between spherical harmonic coefficients $\left<a_{lm}a^{\star}_{l^{\prime}m^{\prime}\right>}$ only when $l=l^{\prime}$ and $m=m^{\prime}$. But because of the presence of Hemispherical Power...

In the present work, we have constructed an anisotropic dark energy cosmological model in the framework of General Relativity at the backdrop of spatially homogeneous and anisotropic Bianchi V metric. The anisotropic behaviour of the model is simulated through the consideration of different scale factors and Hubble expansion rates along different spatial directions. A parameter $m$ is...
