An Accurate Reconstruction of CMB E Mode Signal over Large Angular Scales using Prior Information of CMB Covariance Matrix in ILC Algorithm
Ujjal Purkayastha, Vipin Sudevan, Rajib Saha
In the recent years, the internal-linear-combination (ILC) method was investigated extensively in the context of reconstruction of Cosmic Microwave Background (CMB) temperature ani…

Separating CMB Stokes Q and U polarization signals from Non-Gaussian Emissions
Ujjal Purkayastha, Rajib Saha
In this paper we estimate diffuse foreground minimized Cosmic Microwave Background (CMB) Stokes Q and U polarization maps based upon the fundamental concept of Gaussian nature of C…
