Details of research theme

【Title of Research Theme】
Archival Data Analysis and Simulation for the Next Generation of High Precision Cosmic Microwave Background Radiation (CMB) Observations

 

【Details of Research Theme】

Primordial gravitational waves generated by Cosmic inflation should have imprinted a characteristic "B-mode polarization" in the CMB, which is considered evidence of the inflation. The world is now competing to detect this microscopic signal for the first time, and JAXA's LiteBIRD is the only spacecraft that will be able to achieve this goal. The biggest obstacle in detecting B-mode polarization from high-precision CMB observation data is the "foreground radiation" in the Galaxy, and its accurate estimation is the key to the mission's success. Therefore, this study will be conducted with the following goals:
(1) Create the most accurate foreground radiation model ever by combining archived data with complementary performance, such as AKARI, Planck, WMAP, and COBE. Make it publicly available and contribute to the global CMB community.
(2) Using the CMB archive data and its foreground radiation model, we aim to create new scientific results, such as setting a limit on the upper limit of B-mode polarization.
(3) Perform large-scale simulations of LiteBIRD observations using various foreground radiation models, cosmological models, detector parameters, and observation conditions to demonstrate the feasibility of the mission requirements. In this manner, demonstrate the feasibility of the mission requirements.
