Estimation of Primordial Spectrum with post-WMAP 3 year data
Arman Shafieloo, Tarun Souradeep
In this paper we implement an improved (error sensitive) Richardson-Lucy deconvolution algorithm on the measured angular power spectrum from the WMAP 3 year data to determine the p…
Gravitational wave radiometry: Mapping a stochastic gravitational wave background
Sanjit Mitra, Sanjeev Dhurandhar, Tarun Souradeep +4
The problem of the detection and mapping of a stochastic gravitational wave background (SGWB), either of cosmological or astrophysical origin, bears a strong semblance to the analy…
CMB anisotropy power spectrum using linear combinations of WMAP maps
Rajib Saha, Simon Prunet, Pankaj Jain +1
In recent years the goal of estimating different cosmological parameters precisely has set new challenges in the effort to accurately measure the angular power spectrum of CMB. Thi…
CMB power spectrum estimation with non-circular beam and incomplete sky coverage
Sanjit Mitra, Anand S. Sengupta, Subharthi Ray +2
Over the last decade, measurements of the CMB anisotropy has spearheaded the remarkable transition of cosmology into a precision science. However, addressing the systematic effects…
