Outline

Future observation satellite for the CMB B-mode polarization aims to detect scalar to tensor ratio of 0.1 % level.

In order to go down to this level, the precision of the separation between the CMB and foreground radiation in the millimeter-wave polarization data must be improved by more than one order of magnitude in a precision.

We will achieve this by the following:

Incorporating these results, we will build a computational scheme to carry out the high-precision component separation between the CMB and foreground radiation by utilizing the differences of their physical characteristics.
