CMB bispectrum from primordial magnetic fields on large angular scales
T. R. Seshadri, Kandaswamy Subramanian
Primordial magnetic fields lead to non-Gaussian signals in the Cosmic Microwave Background (CMB) even at the lowest order, as magnetic stresses, and the temperature anisotropy they…
Scalar Field Dark Energy Perturbations and their Scale Dependence
Sanil Unnikrishnan, H. K. Jassal, T. R. Seshadri
We estimate the amplitude of perturbation in dark energy at different length scales for a quintessence model with an exponential potential. It is shown that on length scales much s…
Fractal Dimensions of a Weakly Clustered Distribution and the Scale of Homogeneity
J. S. Bagla, Jaswant Yadav, T. R. Seshadri
Homogeneity and isotropy of the universe at sufficiently large scales is a fundamental premise on which modern cosmology is based. Fractal dimensions of matter distribution is a pa…
Some Consequences of Dark Energy Density varying Exponentially with Scale Factor
Sanil Unnikrishnan, T. R. Seshadri
In this paper we have explored the consequences of a model of dark energy with its energy density varying exponentially with the scale factor. We first consider the model with $ ρ_…
