Study of the Cross Correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam

POLARBEAR is a cosmic microwave background (CMB) polarization experiment in the Atacama desert in Chile. The science goals are to characterize the B-mode signal from gravitational lensing, as well as do a deep search for B-mode signal created by primordial gravitational waves. POLARBEAR started observations in 2012, and has published a series of results from its first and second seasons, including the first measurement of a non-zero lensing B-mode auto-power spectrum. HSC is the wide-field optical/near infrared imager mounted at the prime focus of the Subaru Telescope at the summit of Maunakea. HSC offers the wide field-of-view, superb image quality, and fast and deep imaging capability thanks to the large primary mirror, which makes it one of the best instruments to conduct a weak lensing survey. HSC started a wide, deep galaxy imaging survey from 2014. The cross correlation provides additional tomographic information on the large scale structure and is less sensitive to systematics. We present the status of the cross correlation measurement between CMB polarization lensing and cosmic shear from POLARBEAR and Subaru HSC data. These data are among the deepest maps of the lensing field to date, enabling the measurement of the cross power without the CMB temperature fluctuation.
