Optimal map-making with singularities
Zirui Zhang, Yiwen Wu, Yang Liu +3
In this work, we investigate the optimal map-making technique for the linear system while carefully taking into account singularities that may come from either the covaria…

Study on the filters of atmospheric contamination in ground based CMB observation
Yi-Wen Wu, SiYu Li, Yang Liu +3
The atmosphere is one of the most important contamination sources in the ground-based Cosmic Microwave Background (CMB) observations. In this paper, we study three kinds of filters…

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…
