LiteBIRD kick-off symposium (July 1-2, 2019 at ISAS)

For the LiteBIRD face-to-face meeting on July 3-5, please visit another page.

Description

Observations of the Cosmic Microwave Background (CMB) in the last two decades have revealed astonishing facts of our Universe. We now have precise knowledge on the recent accelerating expansion of our Universe, dark energy and dark matter. In this remarkable development, two satellites for CMB observations, WMAP and Planck, have played the central role.

It is a world-wide consensus that the new frontier of CMB research is the observation of polarization. In particular, it is the most important task in the modern cosmology to test the cosmic inflation hypothesis from measurements of the curl pattern of CMB polarization, which is known as the B-mode.The observation of the B-mode is also expected to open up a new research area of testing quantum gravity theories behind cosmic inflation, including super string theory.

To meet the scientific objectives mentioned above, LiteBIRD is proposed as a strategic L-class satellite of JAXA. As the successor of Planck, and as an international project, its mission is to carry out whole-sky surveys of CMB polarization with unprecedented precision and accuracy.

The main goal of this symposium is to introduce the design concept of LiteBIRD , its expected scientific outputs, the domestic/international collaborations of LiteBIRD, and discuss outcomes of the project. To this end, we also review and discuss science of CMB polarization, current status and future prospects of observations, and how lessons-learned from Planck will be incorporated into the LiteBIRD project.
