"Internal Linear Combination" method for the separation of CMB from Galactic foregrounds in the harmonic domain
R. Vio, P. Andreani
Foreground contamination is the fundamental hindrance to the cosmic microwave background (CMB) signals and its separation from it represents a fundamental question in Cosmology. On…
A theoretical framework for the detection of point-sources in Cosmic Microwave Background maps
R. Vio, P. Andreani
The detection of point-sources in microwave maps is a critical step in the analysis of the Cosmic Microwave Background (CMB) data. If not properly removed, these sources have adver…
European ALMA operations: the interaction with and support to the users
Paola Andreani, Martin Zwaan
The Atacama Large Millimetre/submillimetre Array (ALMA) is one of the largest and most complicated observatories ever built. Constructing and operating an observatory at high altit…
A Modified ICA Approach for Signal Separation in CMB Maps
Robertio Vio, Paola Andreani
AIMS: One of the most challenging and important problem of digital signal processing in Cosmology is the separation of foreground contamination from cosmic microwave background (CM…
