Phase analysis of the 1-year WMAP data and its application for the CMB foreground separation
Pavel D. Naselsky, Oleg V. Verkhodanov, Lung-Yih Chiang +1
We present a new method based on phase analysis for the Galaxy and foreground component separation from the cosmic microwave background (CMB) signal. This method is based on a prev…
Spawning and merging of Fourier modes and phase coupling in cosmological density bispectrum
Lung-Yih Chiang
In the standard picture of cosmological structure formation, initially random-phase fluctuations are amplified by non-linear gravitational instability to produce a final distributi…
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 linear filters for point source extraction of the Planck mission
Lung-Yih Chiang, Pavel Naselsky
The manifestation of point sources in the upcoming PLANCK maps is a direct reflection of the properties of the pixelized antenna beam shape for each frequency, which is related to…
Late reionizations of the Universe and their manifestation in the CMB data
Pavel Naselsky, Lung-Yih Chiang
We investigate two sets of two-epoched reionization models and their manifestation in the CMB anisotropy and polarization data of the recent WMAP project and make some predictions…
