S-Cam and HSC Search of z>6 Quasars
I will present several updates on our high-redshift (z>6) quasar search projects using Subaru/S-Cam and HSC.
In short, our constraints on the quasar luminosity function at z~6 suggest that quasars have only a moderate contribution on the total photons required to re-ionize the universe at z~6.
From the HSC-Wide survey, we have found ~30 low-luminosity quasars
at z>6 in ~100 deg^2 of the HSC-SSP coverage. Their NIR follow-up observation is
now ongoing with Gemini and VLT, which is for the BH mass and metallicity measurements.
Moreover, the HSC-Deep survey enables us to find much fainter quasar candidates down to z~25 AB mag.
