JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EACA34 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Ryo Nagata, High Energy Accelerator Research Organization (KEK) Contact Information: Ryo Nagata rnagata@post.kek.jp Members: Ryo Nagata Abstract Primordial gravitational wave background is generically predicted by cosmic inflation theories. Its amplitude indicates the energy scale of cosmic inflation. LiteBIRD maps the polarization of microwave background sky to detect the signal of the gravitational waves. Since the signal of gravitational wave origin (B-mode・・・<<read more>>
