Title: Two- and three-dimensional wide-field weak lensing mass maps from the Hyper Suprime-Cam Subaru Strategic Program S16A data,
Abstract: We present wide-field (167 deg$^2$) weak lensing mass maps from the Hyper
Supreme-Cam Subaru Strategic Program (HSC-SSP). We compare these weak lensing
based dark matter maps with maps of the distribution of the stellar mass
associated with luminous red galaxies. We find a strong correlation between
these two maps with a correlation coefficient of $\rho=0.54\pm0.03$ (for a
smoothing size of $8'$). This correlation is detected even with a smaller
smoothing scale of $2'$ ($\rho=0.34\pm 0.01$). This detection is made uniquely
possible because of the high source density of the HSC-SSP weak lensing survey
($\bar{n}\sim 25$ arcmin$^{-2}$). We also present a variety of tests to
demonstrate that our maps are not significantly affected by systematic effects.
By using the photometric redshift information associated with source galaxies,
we reconstruct a three-dimensional mass map. This three-dimensional mass map is
also found to correlate with the three-dimensional galaxy mass map.
Cross-correlation tests presented in this paper demonstrate that the HSC-SSP
weak lensing mass maps are ready for further science analyses.
