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…
A Constrained NILC method for CMB B mode observations
Zirui Zhang, Yang Liu, Si-Yu Li +2
The Internal Linear Combination (ILC) method is commonly employed to extract the cosmic microwave background (CMB) signal from multi-frequency observation maps. However, the perfor…
Forecasts of CMB lensing reconstruction of AliCPT-1 from the foreground cleaned polarization data
Jiakang Han, Bin Hu, Shamik Ghosh +14
Cosmic microwave background radiation (CMB) observations are unavoidably contaminated by emission from various extra-galactic foregrounds, which must be removed to obtain reliable…
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…
Performance forecasts for the primordial gravitational wave detection pipelines for AliCPT-1
Shamik Ghosh, Yang Liu, Le Zhang +17
AliCPT is the first Chinese cosmic microwave background (CMB) experiment which will make the most precise measurements of the CMB polarization in the northern hemisphere. The key s…
Forecasts on CMB lensing observations with AliCPT-1
Jinyi Liu, Zeyang Sun, Jiakang Han +18
AliCPT-1 is the first Chinese CMB experiment aiming for high precision measurement of Cosmic Microwave Background B-mode polarization. The telescope, currently under deployment in…
