It is widely known that most massive galaxies harbor a supermassive black hole (SMBH), whose mass reaches up to a few billion times the solar mass, at the nucleus of their host galaxies. However, it is still unclear when and how SMBHs formed and evolved in the early Universe. Some populations of active galactic nuclei (AGNs) are interesting for understanding the evolutionary picture of SMBHs, but their faintness and low number density have prevented us from understanding their statistical properties.
A new wide-field deep optical imaging survey with Hyper Suprime Cam(HSC) on the Subaru Telescope, started in March 2014, enabled us to search for optically-faint AGNs in a wide field (> a few hundreds deg2). In this colloquium, I would like to report some recent outcomes such as discoveries of very high-redshift quasars at z > 6, statistical properties of heavily dust-obscured AGNs, and new pictures of radio galaxies.
