CMB polarization map derived from the WMAP 5 year data through Harmonic Internal Linear Combination
Jaiseung Kim, Pavel Naselsky, Per Rex Christensen
We have derived whole-sky CMB polarization maps from the WMAP 5 year polarization data, using the Harmonic Internal Linear Combination (HILC) method. Our HILC method incorporates s…
CMB map derived from the WMAP data through Harmonic Internal Linear Combination
Jaiseung Kim, Pavel Naselsky, Per Rex Christensen
We are presenting an Internal Linear Combination (ILC) CMB map, in which the foreground is reduced through harmonic variance minimization. We have derived our method by converting…
Understanding the WMAP Cold Spot mystery
Pavel D. Naselsky, Per Rex Christensen, Peter Coles +3
The first and third year data releases from the WMAP provide evidence of an anomalous Cold Spot (CS) at galactic latitude b=-57deg and longitude l=209deg. We have examined the prop…
First Release of Gauss-Legendre Sky Pixelization (GLESP) software package for CMB analysis
A. G. Doroshkevich, P. D. Naselsky, O. V. Verkhodanov +5
We report the release of the Gauss--Legendre Sky Pixelization (GLESP) software package version 1.0. In this report we present the main features and functions for processing and man…
Gauss--Legendre Sky Pixelization (GLESP) for CMB maps
A. G. Doroshkevich, P. D. Naselsky, O. V. Verkhodanov +5
A new scheme of sky pixelization is developed for CMB maps. The scheme is based on the Gauss--Legendre polynomials zeros and allows one to create strict orthogonal expansion of the…
On the Antenna Beam Shape Reconstruction Using Planet Transit
P. D. Naselsky, O. V. Verkhodanov, P. R. Christensen +1
The calibration of the in-flight antenna beam shape and possible beamdegradation is one of the most crucial tasks for the upcoming Planck mission. We examine several effects which…
