Planck LFI: Comparison Between Galaxy Straylight Contamination and other Systematic Effects
C. Burigana, D. Maino, K. M. Górski +7
The straylight contamination due to the Galactic emission (GSC, Galaxy Straylight Contamination) entering at large angles from the antenna centre direction may be one of the most c…
Power spectrum of the polarized diffuse Galactic radio emission
C. Baccigalupi, C. Burigana, F. Perrotta +5
We have analyzed the available polarization surveys of the Galactic emission to estimate to what extent it may be a serious hindrance to forthcoming experiments aimed at detecting…
Data Streams from the Low Frequency Instrument On-Board the Planck Satellite: Statistical Analysis and Compression Efficiency
M. Maris, D. Maino, C. Burigana +1
The expected data rate produced by the Low Frequency Instrument (LFI) planned to fly on the ESA Planck mission in 2007, is over a factor 8 larger than the bandwidth allowed by the…
Neural networks and separation of Cosmic Microwave Background and astrophysical signals in sky maps
C. Baccigalupi, L. Bedini, C. Burigana +8
The Independent Component Analysis (ICA) algorithm is implemented as a neural network for separating signals of different origin in astrophysical sky maps. Due to its self-organizi…
