MATSUMURA Tomotake

MATSUMURA Tomotake is a faculty member in the PHY department at The University of Tokyo. His research focuses on observational and experimental cosmology, particularly the physics of the early universe through measurements of cosmic microwave background (CMB) polarization. He is actively involved in the LiteBIRD mission, a post-ESA Planck satellite project aimed at measuring CMB B-mode polarization. MATSUMURA also contributes to the POLARBEAR/Simons Array and PILOT projects, working on hardware development, calibration, and data analysis. His work includes the design of polarization modulators and the study of systematic effects in CMB experiments.

Tomotake Matsumura is a cosmologist specializing in the study of the cosmic microwave background (CMB) and its polarization. His research focuses on understanding the early universe through observations of the CMB, particularly the detection of B-mode polarization, which is crucial for probing cosmic inflation. He has contributed to several key projects, including the LiteBIRD satellite mission, which aims to conduct all-sky surveys of CMB polarization. His work also involves analyzing data from experiments such as POLARBEAR, BICEP, and EBEX, which are designed to measure CMB polarization with high precision. His research has provided insights into cosmic birefringence, primordial magnetic fields, and the effects of gravitational lensing on the CMB.
