A Foreground Model Independent Bayesian CMB Temperature and Polarization Signal Reconstruction and Cosmological Parameter Estimation over Large Angular Scales
Albin Joseph, Ujjal Purkayastha, Rajib Saha
Recent CMB observations have resulted in very precise observational data. A robust and reliable CMB reconstruction technique can lead to efficient estimation of the cosmological pa…
A Partial-Sky Gibbs ILC Approach for the Estimation of CMB Posterior over Large Angular Scales of the Sky
Vipin Sudevan, Ujjal Purkayastha, Rajib Saha
In this article we present a formalism to incorporate the partial-sky maps to the Gibbs ILC algorithm to estimate the joint posterior density of the Cosmic Microwave Background (CM…
A Foreground Model Independent Estimation of Joint Posterior of CMB E mode Polarization over Large Angular Scales
Ujjal Purkayastha, Vipin Sudevan, Rajib Saha
Ever since Cosmic Microwave Background (CMB) signal is being measured by various satellites based observations with increasing experimental accuracies there has been a parallel inc…
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…
