Extracting Dense and Connected Subgraphs in Dual Networks by Network Alignment
Pietro Hiram Guzzi, Emanuel Salerno, Giuseppe Tradigo +1
The use of network based approaches to model and analyse large datasets is currently a growing research field. For instance in biology and medicine, networks are used to model inte…
Planck intermediate results. XXII. Frequency dependence of thermal emission from Galactic dust in intensity and polarization
Planck Collaboration, P. A. R. Ade, M. I. R. Alves +177
Planck has mapped the intensity and polarization of the sky at microwave frequencies with unprecedented sensitivity. We make use of the Planck 353 GHz I, Q, and U Stokes maps as du…
Planck intermediate results. XII: Diffuse Galactic components in the Gould Belt System
Planck Collaboration, P. A. R. Ade, N. Aghanim +179
We perform an analysis of the diffuse low-frequency Galactic components in the Southern part of the Gould Belt system (130^\circ\leq l\leq 230^\circ and -50^\circ\leq b\leq -10^\ci…
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…
Planck Early Results. V. The Low Frequency Instrument data processing
A. Zacchei, D. Maino, C. Baccigalupi +146
We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discus…
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…
Component separation methods for the Planck mission
S. M. Leach, J. -F. Cardoso, C. Baccigalupi +27
The Planck satellite will map the full sky at nine frequencies from 30 to 857 GHz. The CMB intensity and polarization that are its prime targets are contaminated by foreground emis…
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…
