Auto and cross correlation of phases of the whole-sky CMB and foreground maps from the 1-year WMAP data
Lung-Yih Chiang, Pavel D. Naselsky
The issue of non-Gaussianity is not only related to distinguishing the theories of the origin of primordial fluctuations, but also crucial for the determination of cosmological par…
Foreground analysis from the 1-year Wilkinson Microwave Anisotropy Probe (WMAP) data
Pavel D. Naselsky, Oleg V. Verkhodanov, Lung-Yih Chiang +1
We present a detailed analysis on the phases of the WMAP foregrounds (synchrotron, free-free and dust emission) of the WMAP K-W bands in order to estimate the significance of the v…
Primordial magnetic field and non-Gaussianity of the 1-year Wilkinson Microwave Anisotropy Probe (WMAP) data
Pavel D. Naselsky, Lung-Yih Chiang, Poul Olesen +1
Alfven turbulence caused by statistically isotropic and homogeneous primordial magnetic field induces correlations in the cosmic microwave background anisotropies. The correlations…
