About Our Group

Our research interest is to explore the physical origin of the Universe through the measurements of Cosmic Microwave Background (CMB) polarization. By detecting the CMB B-mode polarization precisely, we attempt to disclose the true figure of the Universe in the time shortly before the Big Bang.

The current research topics are the followings:

* Highly sensitive ground-based CMB polarization experiments (QUIET, POLAEBEAR)

* Mission study of the CMB polarization satellite, LiteBIRD.

* R&D of the highly sensitive large-format detector array for the next-generation CMB polarization experiments as a part of the KEK Detector Technology Project.

We work closely with both domestic and international collaborators for
these projects. In Japan we are the core members to promote the five-year research project approved by MEXT from 2009 to 2013 (see below). From overseas we closely collaborate with the University of Chicago, the University of California, Berkeley and other universities.
