Estimating weak lensing convergence correlation of Type-Ia supernovae from 5-year SNLS data by internal error estimate technique
Ayan Mitra, Arnab Paul, Barun Pal +1
We report non-zero weak lensing convergence correlation signal of Type-Ia supernovae from 5-year Supernovae Legacy Survey data. For our analysis we utilize 296 supernovae magnifica…
Constraints on quintessence scalar field models using cosmological observations
Weiqiang Yang, M. Shahalam, Barun Pal +2
We consider a varieties of quintessence scalar field models in a homogeneous and isotropic geometry of the universe with zero spatial curvature aiming to provide stringent constrai…
Reconstruction of Convergence power spectrum from SNLS weak lensing data
Ayan Mitra, Barun Kumar Pal, Supratik Pal
We estimate the lensing convergence power spectrum from supernovae magnification data using real space correlation function technique. For our analysis we have utilized 296 superno…
Theoretical and observational aspects of cosmological inflation
Barun Kumar Pal
This thesis piles up the results of five works in the field of cosmological inflation, inflationary cosmological perturbations, cosmic microwave background(CMB) and weak gravitatio…
