Forecast of CMB TB and EB correlations for AliCPT-1
Jiazheng Dou, Shamik Ghosh, Larissa Santos +1
The correlations between T, E modes and B modes in cosmic microwave background (CMB) radiation, which are expected to vanish under parity symmetry, have become a sensitive probe of…

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…

Foreground removal with ILC methods for AliCPT-1
Jiazheng Dou, Shamik Ghosh, Larissa Santos +1
One of the main goals of most future CMB experiments is the precise measurement of CMB B-mode polarization, whose major obstacle is the Galactic foregrounds. In this paper, we eval…
