Forecast of foreground cleaning strategies for AliCPT-1
Junzhou Zhang, Shamik Ghosh, Jiazheng Dou +18
We report the test results of several independent foreground-cleaning pipelines used in the Ali CMB Polarization Telescope experiment (AliCPT-1), a high-altitude CMB imager in the…
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…
Fast scalar quadratic maximum likelihood estimators for the CMB B-mode power spectrum
Jiming Chen, Shamik Ghosh, Hao Liu +9
Constructing a fast and efficient estimator for the B-mode power spectrum of cosmic microwave background (CMB) is of critical importance for CMB science. For a general CMB survey,…
Reconstructing simulated CMB polarization power spectra with the Analytical Blind Separation method
Larissa Santos, Jian Yao, Le Zhang +6
Multi-frequency observations are needed to separate the CMB from foregrounds and accurately extract cosmological information from the data. The Analytical Blind Separation (ABS) me…
