Foreground removal from WMAP 5 yr temperature maps using an MLP neural network
Aims. One of the main obstacles for extracting the cosmic microwave background (CMB) signal from observations in the mm/sub-mm range is the foreground contamination by emission from Galactic component: mainly synchrotron, free-free, and thermal dust emission. The statistical nature of the intrinsic CMB signal makes it essential to minimize the systematic errors in the CMB temperature determinat...

متن کاملLensed CMB temperature and polarization maps from the Millennium Simulation
We have constructed the first all-sky CMB temperature and polarization lensed maps based on a high-resolution cosmological N -body simulation, the Millennium Simulation (MS). We have exploited the lensing potential map obtained using a map-making procedure (Carbone et al. 2008) which integrates along the line-of-sight the MS dark matter distribution by stacking and randomizing the simulation bo...
متن کاملDestriping CMB temperature and polarization maps
We study destriping as a map-making method for temperature-and-polarization data for cosmic microwave background observations. We present a particular implementation of destriping and study the residual error in output maps, using simulated data corresponding to the 70 GHz channel of the Planck satellite, but assuming idealized detector and beam properties. The relevant residual map is the diff...
متن کاملForeground contamination of the WMAP CMB maps from the perspective of the matched circle test
WMAP has provided CMB maps of the full sky. The raw data is subject to foreground contamination, in particular near to the Galactic plane. Foreground cleaned maps have been derived, e.g., the internal linear combination (ILC) map of Bennett et al. (2003), and the reduced foreground TOH map of Tegmark et al. (2003). Using S statistics we examine whether residual foreground contamination is left ...
