Abstract

In 2022, Subaru is entering a new stage called ”Subaru-2” which will be realized by the three wide-field facility instruments. The first one is the Hyper Suprime-Cam (HSC), the prime focus optical imager with 1.5 deg FoV. It started the science operation in 2014 and completed the strategic survey program last year with total of 330 observing nights. The second instrument is the Prime Focus Spectrograph (PFS), which is an optical to nearinfrared multiobject fiber spectrograph with a similar FoV to HSC. In 2021, it started engineering observations with all of the delivered subsystems; the Prime Focus Instrument, Spectrograph Module 1, Fiber Cable System 1, and Metrology Camera System. The commissioning and installation of the other subsystems will continue in 2022-2023. The third system is the ULTIMATE-Subaru which consists of the Ground Layer AO (GLAO) system and wide-field near-infrared instruments. The conceptual design review of the instruments was done in 2021, and the preliminary design review of the GLAO system is planned in 2022. Among the existing facility instruments, the Adaptive Optics system, AO188, is undergoing active upgrades which include the new laser guide star system, real-time computer system, deformable mirror, NIR wavefront sensor, and relay optics to quickly switch the downstream science instruments. We will also present the status and plan of the other facility instruments as well as the visitor instruments.
