At Kavli IPMU, we are using large telescopes on the ground and in space to understand the evolution of galaxies and their supermassive black holes out to the distant reaches of our Universe. In particular, we are conducting a wide and deep optical survey of the extragalactic sky with Subaru Telescope using Hyper Suprime Cam (SHC) and planning the next generation large spectroscopic surveys with Prime-Focus Spectrograph (PFS). Complementing these efforts, we are mapping the spatial distribution of the molecular gas and dust in distant star-forming galaxies and Active Galactic Nuclei (AGN) with ALMA to shed light on the physical drivers of the global star formation and black hole accretion history.
