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_…
CMB Anisotropy Due to Tangled magnetic fields in re-ionized models
T. R. Seshadri, Kandaswamy Subramanian
Primordial tangled cosmological Magnetic Fields source rotational velocity perturbations of the baryon fluid, even in the post-recombination universe. These vortical modes inturn l…
Cosmic Microwave Background Polarization Signals from Tangled Magnetic Fields
T. R. Seshadri, Kandaswamy Subramanian
Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface (LSS) of the cosmic microwave background radiation (CMBR).…
Nature of Clustering in the Las Campanas Redshift Survey
Somnath Bharadwaj, A. K. Gupta, T. R. Seshadri
We have carried out a multi-fractal analysis of the distribution of galaxies in the three Northern slices of the Las Campanas Redshift Survey. Our method takes into account the sel…
