2. Foreground removal pipeline in AliCPT

Le Zhang (SJTU)

In this talk, I will give a short summary of the foreground removal pipeline in AliCPT. which includes a description of all foreground-removal methods used in our data analysis. I will also report the latest results by applying all these methods into the real Planck data maps and simulated future-like maps with very low noise level.

The polarization map of AliCPT can be combined together with the Planck temperature map to reconstruct the CMB lensing map. The benefit is the quality of AliCPT polarization. The reconstructed CMB lensing map can be apply to either auto-correlation or cross-correlation with other LSS surveys (galaxy survey or shear survey). We introduce the current status of CMB lensing cross-correlations,...

15. RECONSTRUCTING SIMULATED CMB POLARIZATION POWER SPECTRA WITH THE ANALYTICAL BLIND SEPARATION METHOD

We applied the Analytical Blind Separation (ABS) method, that extracts CMB signal from its contaminants, to simulated sky polarization maps, in order to test its ability to recover CMB E− andB−mode power spectra in the presence of two polarized foreground components, namely synchrotron and thermal dust, and an uncorrelated Gaussian distributed instrumental noise. We used multi- frequency Q and...

34. Data analysis pipeline and noise simulation for AliCPT

Dr Siyu Li (IHEP)

In this talk I will report a prototype of map-making pipeline by the AliCPT science team, then present the simulated noise maps and part of the results on the scientific forecast
