Forecasts of CMB -mode anomalies for AliCPT-1
Jiazheng Dou, Wen Zhao
The standard CDM model has been highly successful in describing cosmic microwave background (CMB) observations. Nevertheless, a set of large-scale statistical anomalies persists…
Forecasts of constraining isotropic cosmic birefringence on AliCPT-1
Jiazheng Dou, Wen Zhao
Cosmic birefringence (CB) is a promising probe of parity-violating physics beyond the Standard Model, characterized by the rotation of the linear polarization plane of cosmic micro…
Forecasts of effects of beam systematics and deprojection on the third-generation ground-based cosmic microwave background experiment
Jiazheng Dou, Jiakang Han, Wen Zhao +1
The ground-based cosmic microwave background (CMB) experiments are susceptible to various instrumental errors, especially for -mode measurements. The difference between the resp…
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…
