Consistency tests for Planck and WMAP in the low multipole domain
Anne Mette Frejsel, Martin Hansen, Hao Liu
Recently, full sky maps from Planck have been made publicly available. In this paper, we do consistency tests for the three Planck CMB sky maps. We assume that the difference betwe…
Can residuals of the Solar system foreground explain low multipole anomalies of the CMB ?
M. Hansen, J. Kim, A. M. Frejsel +4
The low multipole anomalies of the Cosmic Microwave Background has received much attention during the last few years. It is still not ascertained whether these anomalies are indeed…
Faraday Rotation as a diagnostic of Galactic foreground contamination of CMB maps
M. Hansen, W. Zhao, A. M. Frejsel +3
The contribution from the residuals of the foreground can have a significant impact on the temperature maps of the Cosmic Microwave Background (CMB). Mostly, the focus has been on…
Symmetry and anti-symmetry of the CMB anisotropy pattern
Jaiseung Kim, Pavel Naselsky, Martin Hansen
Given an arbitrary function, we may construct symmetric and antisymmetric functions under a certain operation. Since statistical isotropy and homogeneity of our Universe has been a…
Pearson's random walk in the space of the CMB phases: evidence for parity asymmetry
M. Hansen, A. M. Frejsel, J. Kim +2
The temperature fluctuations of the Cosmic Microwave Background (CMB) are supposed to be distributed randomly in both magnitude and phase, following to the simplest model of inflat…
The Gauss-Legendre Sky Pixelization for the CMB polarization (GLESP-pol). Errors due to pixelization of the CMB sky
Andrei G. Doroshkevich, Oleg V. Verkhodanov, Pavel D. Naselsky +6
We present developing of method of the numerical analysis of polarization in the Gauss--Legendre Sky Pixelization (GLESP) scheme for the CMB maps. This incorporation of the polariz…
