Correlated Component Analysis for diffuse component separation with error estimation on simulated Planck polarization data
S. Ricciardi, A. Bonaldi, P. Natoli +6
We present a data analysis pipeline for CMB polarization experiments, running from multi-frequency maps to the power spectra. We focus mainly on component separation and, for the f…
A Bayesian technique for the detection of point sources in CMB maps
F. Argueso, E. Salerno, D. Herranz +3
The detection and flux estimation of point sources in cosmic microwave background (CMB) maps is a very important task in order to clean the maps and also to obtain relevant astroph…
Joint Bayesian separation and restoration of CMB from convolutional mixtures
K. Kayabol, J. L. Sanz, D. Herranz +2
We propose a Bayesian approach to joint source separation and restoration for astrophysical diffuse sources. We constitute a prior statistical model for the source images by using…
Adaptive Langevin Sampler for Separation of t-Distribution Modelled Astrophysical Maps
K. Kayabol, E. E. Kuruoglu, J. L. Sanz +3
We propose to model the image differentials of astrophysical source maps by Student's t-distribution and to use them in the Bayesian source separation method as priors. We introduc…
