The polarization quaternion and its applications: a joint representation of the Q/U Stokes parameters and E/B mode polarizations
Hao Liu, James Creswell, Chao-Wei Tsai +1
In this work, we point out that the Q/U Stokes parameters and E/B mode polarizations are the four components of a unique quaternion, which describes at the same time the directions…
Ring of attraction: overlapping directions of the dipole modulation of the CMB, the parity asymmetry, and kinematic dipole percolation zone
James Creswell, Pavel Naselsky
The largest anisotropy in the cosmic microwave background (CMB) is the 3 mK kinematic dipole reflecting our motion with respect to the CMB frame and pointed in the direction $(l, b…
Asymmetry of the CMB map: local and global anomalies
James Creswell, Pavel Naselsky
We investigate the sources of parity asymmetry in the CMB temperature maps using a pixel domain approach. We demonstrate that this anomaly is mainly associated with the presence of…
Statistics of non-polarized points in the CMB polarization maps
Jaan Kasak, James Creswell, Hao Liu +1
The non-polarized points (NPP) of the and Stokes parameters of the CMB can be classified according to the geometry of the polarization field. We describe a procedure to ide…
Comparison of the Planck 2018 CMB polarization maps in the BICEP2/Keck region
Hao Liu, James Creswell, Pavel Naselsky
We examine the statistical properties of polarization maps from Planck 2018 within the patch of sky observed by the BICEP2/Keck experiment using the one point distribution function…
Statistics of CMB polarization angles
James Creswell, Nadia Dachlythra, Hao Liu +2
We study the distribution functions of the CMB polarization angle , focusing on the Planck 2018 CMB maps. We extend the model of Preece & Battye (2014) of Gaussian correlated $Q…
