An overview of current and future instrumentation at the Subaru telescope

Abstract

In the past few years, a new prime focus optical imager Hyper Suprime-Cam (HSC), which has 1.5 deg field of view (FoV), is commissioned and started its science operation. Prime-Focus Spectrograph (PFS), which is an optical to near-infrared multiplexed spectrograph over 1.3 deg FoV is currently in the construction phase and will be a next facility instrument to promote the wide-field astronomy at Subaru together with HSC. As a new facility instrument program, ULTIMATE-Subaru, which will develop wide-field near-infrared instruments with the aid of ground-layer adaptive optics system, is being planned. In addition to the new facility instruments, upgrades of the existing facility instruments and developments of several visitor instruments are in progress. This paper gives an overview of current and future instrumentation at the Subaru telescope.
