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…
