Yusuke (Ph.D. student) visited the Kavli IPMU, University of Tokyo, to work on the systematic error of LiteBIRD with Prof. Matsumura (Univ. Tokyo) and other CMB researchers at IPMU. Patricia Diego (MPA), who is staying at IPMU, also participated in the discussion and greatly contributed to the study of systematic error theory.
Yusuke is working on a theory for fast estimation and suppression of systematic errors that degrades with CMB polarization observations [Y. Takase et al. 2024, arXiv]. IPMU is responsible for the development of the Polarization Modulator Unit (PMU) on the LiteBIRD low-frequency telescope, which will be used to unify systematic effects originating from the imperfection of the PMU. We discussed with students from Matsumura Lab. an analytical method to treat systematic effects originating from the imperfection of the PMU in a unified manner.
The activity is also introduced in the HP of Kavli IPMU CMB group.
