||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.
